A Critical Measurement You Simply Can't Estimate
Here is a service that you and every gunsmith in the world should be offering all shotgun shooters. But, because of a lack of proper instructions and tools, plus the fact that most shooters do not know that a cure exists, the correction has been offered by only a handful of aware gunsmiths. These men have made heroes of themselves (and money) in their trade areas. This, you too, can and should do. It is profitable . . . the guns need it . . . and the shooters want it! The trapshooting customer will love you, the skeet shooter will offer to beat up your enemies and the hunter will swear you have performed a miracle on his old Bess! By reworking an improper chamber you will reduce recoil, shot deformation, target or game-missing "free holes" and improve patterns. And all you need are the Gauges, the proper chamber and Forcing Cone Reamers, and the Instructions we furnish, to give the gun the right chamber dimensions for modern, star crimped, plastic shells. Just like that, and you are making a lot of people happy, a reputation for yourself as a knowledgeable shotgun man, and a respectable profit. An unbeatable combination!
Not Just Choke Alone
It is generally believed that the "right choke" has everything to do with pattern, recoil and performance. Choke is important, but of equal or more importance are the configuration of the chamber and forcing cone and how all three - choke, cone and chamber - work together.
Millions of Shotguns Just Waiting
There are millions (!) of shotguns in use today with the obsolete "short" chambers and forcing cones incapable of delivering a passable pattern without "free holes" when shooting modern, star-crimped shells. And, because of these obsolete chambers, they kick your teeth out and punch the action unnecessarily with higher pressures while performing far below expected standards.
Obsolete Chamber
The problem with chambers is that, over the years, there have been a great variety of "correct depths" used for the shells then currently being manufactured, many of them shorter than 2-¾" or 3" overall length of the fired cases of today's plastic shell. Couple this with a short Forcing Cone (the taper from chamber diameter to bore diameter) and the results are: deformed shot; distorted patterns; torn hulls; excessive kicking and pressure. That crimp must have room to unfold completely flat when the shot and wad go from case to bore. Any little bit of case forced into their path because of a short chamber spells trouble with a capital "T".
Gauge Tells It All
The purpose of the Chamber Gauge is threefold: First, and most important, to check your work when doing a chamber job for a customer; Second, to identify obsolete, too-short chambers on guns brought in for service, and Third, to demonstrate to your shooters why their guns are not performing to their full capabilities.
