In some instances, part of the bullet, especially lead bullets, will be forcedfrom between the cylinder and the barrel. This is often referred to as “spit-ting”or “shaving”lead.It is dangerous to the shooter as well as to bystanders.As you would expect, the potential accuracy of a revolver is greatly dimin-ished, because the bullet is deformed prior to its entry into the bore. Also,bullet weight is no longer consistent.

Firearms manufacturers developed the forcing cone as a means of com-pensating for cylinder-to-bore misalignment brought about either by wearon the various parts of the mechanism, or by inconsistency in the manufac-turing process.

It has only been within the last few years that the significance of the forc-ing cone as an element of revolver accuracy has begun to be fully realized.The growth of revolver competition, and the demand for greater accuracy inrevolvers, has played a major role in focusing more attention on the forcingcone because a well-designed and constructed forcing cone allows for thesmooth entry of the bullet into the bore.The goal is to have minimum bulletdeformation which, in turn, will lead to greater accuracy. A properly con-structed forcing cone aids in minimizing lead buildup or “leading” in thebore.Again,this causes less bullet deformation,more uniform pressures andcontributes significantly toward greater accuracy.

The Brownells Revolver Chamfer Tool Kit was designed with the assis-tance and cooperation of noted professional pistolsmith, Ron Power, whosemany years of building some of the finest PPC revolvers in the U.S. broughtinvaluable experience and expertise to the project. Until the introduction ofthis Kit, tools of this type were almost impossible to obtain commercially,and even the most proficient pistolsmiths seldom had chamfering tools ofsuch excellent design and high quality for use in the modern revolver. Theforcing cone is a very critical and sensitive area that greatly affects accura-cy and reliability.Very little has been written on how to correct the problemsthat are directly traceable to faults in forcing cone design or function.

With these very detailed and complete instructions - plus the BrownellsRevolver Chamfering Tool Kit and the other accessories - you can now makeforcing cone work an important part of the service you offer your customersand a profitable part of your operation. You’ll be very pleased with the re-sults you can achieve.NOTE: We urge you to read all of these instructions carefully and thor-oughly, prior to doing any work.You will be dealing with a critical area of therevolver; there is little room for error. Be Careful!

THE FORCING CONEFUNCTION AND SIGNIFICANCE

Although forcing cones are found in one form or another in almost everymodern breech-loading firearm, it is of no importance whether the revolveris singe-action, double-action, .22 rimfire or .44 magnum. The forcing cone,or barrel throat, always functions in the same manner and is extremely im-portant to the safety, reliability and accuracy of the receiver.

The forcing cone is located at the breech end of the barrel, immediately infront of the cylinder. It can be thought of as a “funnel” or internal taper atthe beginning of the barrel. The function of the forcing cone is to guide thebullet into the bore after it has left the cylinder. The forcing cone may varyin length up to 3⁄8" or more, and the angle of internal taper may range fromless than 1° to 45° or more.

Modern firearms manufacturers employ some incredibly sophisticatedand advanced production techniques. But, it is still not financially practicalto produce a revolver in which all six chambers of the cylinder align them-selves perfectly with the bore of the barrel under all conditions.As a revolveris used and develops cylinder/frame wear, the alignment of the individualcylinder chambers with the barrel bore deteriorates. Under certain condi-tions, this misalignment can progress to a dangerous condition.

Extreme cases result in the cylinder chamber being so far out of align-ment with the barrel bore that the bullet hits the side of the barrel as itleaves the cylinder. It then “skids” into the bore and continues on down thebarrel. This condition results in very poor accuracy.

BROWNELLS REVOLVERCHAMFERING TOOL KITS

The Brownells Revolver Chamfering Tools are available as individualitems and in a variety of kits.Let’s begin by examining each tool in the Com-plete Gunsmith’s Chamfering Tool Kit and its function.

FIGURE 1 - Complete Certerfire Kit

The Extension Rod (“A”, Fig. 1) is approximately 111⁄2" long, made ofhigh-strength stainless steel and threaded at one end to accept a variety ofcutters and laps. The other end has a small, flat area, milled into one sideapproximately 1⁄8" from the end. This milled area was designed to provide alocking surface for the tool handle.

The Handle (“B”,Fig.1) is secured to the Extension Rod by a small Allenset screw. A 3⁄32" Allen wrench is also provided. (One note of caution at thispoint. It is not necessary to apply a great deal of pressure to the Allen screwwhen attaching the Handle to the Extension Rod. Make it snug and thenstop. You don’t want to strip out the screw threads.)

An Aluminum Center Guide (“C”, Fig. 1) is provided to both protectthe muzzle of the barrel from possible damage by the Extension Rod and toensure that the Extension Rod is centered in the bore. It is utilized by slid-ing the guide onto the Extension Rod so its tapered portion will extend downinto the bore during use. The Extension Rod is then inserted through thebarrel from the muzzle end.

The Chamfering Cutter (“D”, Fig. 1) is threaded onto the ExtensionRod after the appropriate Brass Pilot is in place.Three Chamfering Cuttersare provided: an 18° Cutter for 9mm to .41 caliber barrels; an 18° Cutterfor .44 caliber to .45 caliber barrels; an 11° Cutter covering all calibers from9mm to .45. Also available is a 5° Cutter for .38/.357 which duplicates theRuger factory chamfer for these calibers. The 18° chamfer has been used

FIGURE 2 - 11° Cutter positioned in barrel throat

quite often by firearms manufacturers, and in most instances, will providea slight accuracy advantage when shooting jacketed bullets.The 11° Cutterwas designed by Ron Power after extensive research and experimentationduring which Ron found that the 11° chamfer provided optimum accuracywhen using hollow-base lead wadcutter bullets, the type most often used inPPC guns.

Additionally, two 82° Cutters (“E”, Fig. 1) (9mm to .41 caliber and .44 to.45 caliber) are available to slightly chamfer the inside edge of the rear ofthe forcing cone.These Cutters are used only after the forcing cone has beencut. Their function is to break the sharp corner that may be present on theinside edge of the barrel chamfer.DO NOT use the 82° Cutter to form a com-pound angle forcing cone.Test results have shown this is detrimental to goodaccuracy.

The Breaker Bar (“F”, Fig 1) is provided for use as an aid in removingthe various cutters from the Extension Rod. Slots are provided in the end ofeach cutter for its use. DO NOT attempt to remove cutters with pliers orvise grips. Doing so risks almost certain damage.

Brass Laps (“G”, Fig 1) in various calibers and 11° or 18° are availablefor those gunsmiths who wish to polish or lap the chamfer cut. After the fi-

nal cut has been made, the proper Brass Lap is attached to the ExtensionRod and an abrasive such as the Brownell Abrasive Compound used to coatthe lap. The extension Rod is then rotated in a clockwise direction while thelap is pulled into the chamber. Normally, very little (if any) polishing is re-quired.

The Brass Pilots (“H”, Fig 1), which are available in five sizes (.32, .38,.41, .44, and .45), are very desirable accessory items. By utilizing a Brass Pi-lot, you can, in many instances, recut or realign off-center forcing cones.ThePilot also aids in ensuring that the Chamfering Cutter is in proper align-ment with the axis of the bore during use in the installation of new barrels.It is mandatory that a Brass Pilot be used when utilizing a 90° Facing Cut-ter.

FIGURE 3 - 90° Facing Cutter - Note clearance between Cutter and top strap

The 90° Facing Cutter (“J”, Fig. 1) is used to square up the breech endof the barrel.This is especially useful when fitting a new barrel to a revolver.The use of the Facing Cutter can make this job faster, easier and much moreprecise, and is just the ticket for removing “high” spots on the barrel whichmay interfere with cylinder rotation.

The 90° Facing Cutters are available in four diameters: .450, .560, .625and 687. You should use the Cutter whose diameter just exceeds the diam-eter of the end of the barrel extension. It should never be smaller than theextension diameter. Ideally, it should just exceed the diameter of the barrelextension while not being large enough to contact any point on the inside ofthe frame.

The Barrel Chamfering PlugGauges (See Fig. 4) are additional ac-cessory items that are very helpful.Available in five sizes: .22, .32, .38/.357,.44 and .45 to check either 18° or 11°chamfers and in one size (.38/.357) for 5°

chamfers: these precision-ground, hardened steel gauges enable you to ac-curately measure the width of the chamfer and ensure you never remove toomuch metal from the barrel extension.

IMPORTANT: READ BEFORE PROCEEDING

To date, there is no apparent “standard” for forcing cone configurationwithin the firearms industry. Individual manufacturers utilize a great di-versity of designs and, from time to time, change these. Because of this, youMUST always carefully check the configuration of the existing forc-ing cone prior to making any modifications. We suggest the use of theappropriate Brownells Chamfer Plug Gauge following the procedures de-tailed on page 3 of these instructions, plus a good visual inspection.

You will encounter many revolvers with extremely short, almost non-ex-istent forcing cones.These guns can be helped greatly by using the BrownellsRevolver Chamfer Tools. Occasionally, you may encounter a revolver with aforcing cone that is cut too deeply when measured with our Plug Gauges;and some may be larger in diameter than recommended (see Page 3, Col-umn 2, Paragraph 3 of these instructions). When an existing forcing cone iseither too deep or too large, you may be compelled to either accept it as is, orset the barrel back and reface it prior to cutting a new forcing cone. Youshould NEVER recut a forcing cone if doing so will result in a “Stepped” orcompound angle.

USING THE TOOLS

Begin by making sure your revolver is not loaded.While it is not necessaryin most cases, the removal of the cylinder from the gun will make your workeasier and faster. You may also wish to remove the grips and place the butt

sult in an erroneous reading. Carefully place the appropriate caliber gaugein the barrel throat, utilizing the knurled handle. If the lower step of thegauge is above the edge of the barrel extension, then additional chamferingis needed. If the top of the upper step is BELOW the edge of the barrel ex-tension, TOO MUCH material has been removed (See Fig. 6)! The cham-fer should be cut so the lower step is slightly below the edge of the barrel ex-tension, while the top of the upper step is just above the barrel extension(See Fig. 7). While doing barrel chamfering, it is IMPERATIVE that you

check your work FREQUENTLY with a Barrel Chamfering Plug Gauge.In utilizing any of the 90° Facing Cutters on the rear-most portion of the

revolver barrel or barrel extension, you should be aware of several points,especially when fitting a new custom barrel. In no case should the clearancebetween the face of the cylinder and the barrel extension (the cylinder gap)exceed .008". If you have more than .008" cylinder gap, you are almost cer-tain to have lead “spitting” and excessive loss of gas, thereby reducing yourpressure and velocity.

FIGURE 8 - Checking cylinder gap with feeler gauge

Ron Power believes the optimum clearance for the cylinder gap is .006" to.007" (See Fig. 8). According to Ron, the absolute minimum cylinder gapshould be such that with a .004" feeler gauge in place between the face of thecylinder and the barrel extension,you can pull the revolver through the dou-ble action cycle without having the cylinder hang up on the feeler gauge. Inother words, the cylinder should be able to spin freely. With .004", you runthe risk of having a malfunction due to the normal buildup of powder residueand fouling on the face of the cylinder during firing.

The 908 Facing Cutters can also be utilized to remove “high” spots on thebarrel extension which may bear against, or “drag”, on the face of the cylin-der. Again, exercise EXTREME CAUTION when utilizing this Cutter. Ifyou accidentally cut too much and the cylinder gap exceeds .008°, you maybe forced to refit the barrel to the revolver! BE CAREFUL!

After the Cutters have been utilized, you may wish to use the Brass Lap,available for the 11° and 18° chamfers.The Lap is attached to the extensionrod in the same manner as the Cutters. Spread an abrasive compound suchas the Brownell Abrasive Compound Paste on the lap and gently draw it in-to the chamfer. While rotating the lap in a clockwise direction, pull gentlytoward the muzzle. Remove the lap to check the chamfer periodically untilthe desired degree of smoothness is obtained.

Depending upon the finish of the chamfer, you may wish to start lappingwith the Brownell 240 Grit Paste and work up to a mirror finish with the

of the revolver in a suitable padded vise so your hands will be free. The bar-rel can be in almost any position;horizontal,perpendicular or vertical.Placeit in the position most comfortable for you.

It is a good idea at this point to lay a clean shop cloth through the cylin-der opening on the frame in order to catch any stray metal chips, drops ofcutting oil, lapping compound or any other debris that may be removed fromthe barrel. You should also run a cleaning patch or two through the barrelto remove any excessive oil or fouling prior to beginning any work.

Loosen the set screw and place the Chamfering Tool handle on the Ex-tension Rod. The Handle should be secured to the non-threaded end of therod in such a manner that the set screw in the Handle enters the small, flat,milled area on the Extension Rod.Tighten the set screw until the Handle issecure. DO NOT -- repeat DO NOT -- over-tighten the set screw. You maystrip the threads from the Handle.

Place the Center Guide on the Extension Rod so the tapered portion ispointing away from the Handle. The Extension Rod can then be insertedthrough the barrel from the muzzle end. This should be done carefully. TheCenter Guide should then be pushed forward so the tapered portion entersthe barrel bore.

FIGURE 5 - Barrel throat being recut on Colt Diamondback

If you have a Brass Pilot of appropriate caliber, it can be slipped over thethreaded end of the Extension Rod and gently slid into the bore of the bar-rel. It will provide an additional aid in aligning the Cutter and the Exten-sion Rod with the axis of the bore.

A Chamfering Cutter can now be threaded onto the Extension Rod. Posi-tion the Cutter against the threaded portion of the Extension Rod with onehand so by turning the Extension Rod Handle with your other hand in aclockwise direction, the Cutter will be drawn onto the rod. After the Cutteris properly secured to the Extension Rod, you can begin cutting by gentlypulling on the Handle of the Rod and by rotating the Cutting Head in a clock-wise direction.

Cutting oil should always be used with any cutter to increase its effec-tiveness, aid in ensuring that the cuts will be as smooth as possible, and toextend the life of the cutter. NEVER under any circumstances, should theCutter be turned in a counter-clockwise direction while it is being pulled in-to the barrel. To do so will dull and possibly ruin, the cutting edges of thetool.We repeat - NEVER turn any Cutter in a counter-clockwise directon.

You may be surprised at how easily the Cutting Tool operates. Do not getcarried away! It is quite easy to cut more than you should, either when cut-ting a chamfer or facing off a barrel.

When cutting a chamfer, you normally do not want to have the internaldiameter of the rear-most portion of the chamfered area to be over .020" larg-er than the diameter of the bullet of the cartridge that is being used. In oth-er words, in a .38 Special revolver, which utilizes a bullet that is normally.356" to .358" in diameter, the maximum diameter of the chamfer should be .376" to .378". A very simple and easy way to check this, and to ensure youdo not cut more than you should, is to utilize the Brownells Chamfer PlugGauges. By using these Gauges, you can tell at a glance exactly how deep acut should be.Above all, be extremely careful when cutting with this tool. Itis very easy to cut too much. Go slow! Be careful!

The precision ground and hardened Barrel Chamfering Plug Gauges areavailable in .22, .32, .38, .44 and .45 calibers. Each gauge has an integral pi-lot to assure precise alignment with the axis of the bore and to minimizemeasurement error.The most important part of each gauge is the .0256 steplocated at the base of the knurled handle. The top of the lower step and thetop of the upper step represent the minimum and maximum degrees of ac-ceptable chamfering repectively.

These gauges can be used quickly and easily. Begin by carefully cleaningthe throat area of the barrel to remove any oil or metal chips which could re-

It is necessary to utilize three different sizes due to variations in bore di-ameter in .22 caliber handguns. After cleaning the barrel, carefully insertthe Extension Rod which provides the closest, snuggest fit. This ExtensionRod will act as a pilot and will properly center the various cutting tools. Sec-ond, the .22 kit is available only with an 11° Chamfering Cutter. The 18°Chamfering Cutter is not available in .22 caliber.

After you have completed your work with the Chamfering Tools, be sureto check the barrel to ensure you did not leave a Brass Pilot in the bore! It isalso necessary to thoroughly clean the bore with a liquid bore solvent andcleaning patches in order to make certain all metal shavings or traces of lap-ping compound are removed. The bore should be spotless! The frame andother parts of the revolver should also be wiped down and lightly oiled.

We are especially proud of our Chamfering Tools.As with all our tools, weguarantee their quality and construction. If you have any questions relat-ing to their use, or if you have any suggestions for improvements or modifi-cations, please feel free to contact our Technical Services Section by mail orphone.

800 Grit Paste. While a highly polished chamfer sure looks great, it is notnecessary for optimum performance. Also, a highly polished surface willquickly become etched by hot gases from the chamber when the gun is fired.

FIGURE 9 - Chamfer laps in place

While the procedures are identical to those utilized for the larger calibers,the .22 caliber chamfering tools are different in two respects: First, due tothe extremely small bore diameter in a .22, it is not practical to utilize ei-ther a Brass Pilot or a Center Guide. In lieu of these, we have provided threeExtension Rods in .211", .213" and .215" diameters repectively.

REVOLVER CHAMFERING TOOLS & KITSCuts Beautiful, Chatter-Free Chamfer To Eliminate Bullet Splatter, Shaving, and Fouling Buildup - No Lathe Needed, No Need To Remove Barrel From Frame

You don’t have to handle very many revolvers to discover that many of the barrels have only a bare minimum chamfer at the throat, no chamfer at all, or onethat’s off center.Any of these can force lead and jacket material to be sprayed out of the barrel/cylinder gap and do strange things to the bullet shape, and there-fore, accuracy. Plus, fouling will build up between barrel and cylinder, causing the cylinder to drag or lock up. Our Revolver Chamfering Tools are a custom, pre-cision reaming system designed to help you cut a beautiful, chatter-free, perfectly centered chamfer without dismantling the barrel from the frame. The Exten-sion Rod slides into the bore; screw on the Cutter; add the centering cone and the handle, and you’re ready to go. All of the Kits let you choose the angle of theChamfer Cutter, the size of Facing Cutter and the Pilot. All include instructions and come in a see-through-top box with plenty of room to start with a Basic Kitand add more components later.

INDIVIDUAL CHAMFERING TOOLS

5° CHAMFER CUTTER - Super gentle angle as currently used by Ruger on their.38/.357 DA guns. If you set back a Ruger barrel or just want to duplicate this an-gle on any other barrel, use this cutter. You CANNOT use 18° or 11° cutters on a5° throat without exceeding maximum throat diameter or making a compound an-gle.

11° CHAMFER CUTTER - Recommended by Ron Power. The gentler entry anglecauses less bullet deformation and gives better accuracy (especially important for“wadcutter” shooters). One size for all calibers from .38 to .45. Use with pilots inchart.

18° CHAMFER CUTTER - Our “standard” cutter.The angle is right for jacketed bul-lets as well as round nose and semi-wadcutter lead bullets. It will remove most fac-tory cuts without exceeding the maximum recommended throat diameter or cre-ating a compound angle.

Tough, Easy-To-Use,Deep-Colored, Professional Touch-Up Blue

T-4 is in the catalog because of customer demand. As MaynardBuehler said: “THIS is the BEST yet.” Every time a new gun bluecomes on the market, we test it on a piece of gun barrel. We bluethree spots: one with the new blue, one with Oxpho- Blue™ andone with T-4. A day later we start rubbing all three areas withsteel wool until one of them starts wearing off. So far, OxphoBlue™ is toughest and T-4 next. However, for ease of applicationand deep density of color, T-4 is superior.
