Lengthening the forcing cone with this reamer can enhance pattern density, reduce pellet deformation, and lower felt recoil, improving overall shotgun performance.
The reamer's five spiral flutes and hex-drive shank design ensure a smooth cut and compatibility with standard square drive sockets and T-handles.
It is specifically designed for .410 bore shotguns and should not be used on chrome lined bores.
Clymer's "BACK-BORE" reamers are essential for shotgun barrel and choke modifications, available in .005" increments from .725" to .740" for 12 gauge.
These reamers can be used for various purposes including creating constriction in shortened barrels or enlarging bores for competitive shooters.
Made from M-7 high speed steel, the 5" long reamers are designed for durability and efficiency in improving shotgun performance and appearance.
The BACK BORE reamer allows for adding choke constriction to 12 GA. barrels without threading or altering the choke, by stopping the reaming process 2-3 inches before the muzzle.
It is suitable for tightening chokes on barrels that are too thin for screw-in tubes and can restore rusted or pitted barrels to a "like new" condition.
Constructed from M7 high-speed steel, the reamer is 5 inches long, features eight straight flutes, and is designed specifically for 12 gauge shotgun barrels.
The SHOTGUN CHAMBERING REAMERS are made from high-quality M-7 High-Speed Steel for professional gunsmithing.
Finish Reamers are recommended for a few chambers, while Roughers are advised to save wear on Finish Reamers for multiple chambers.
When ordering, specify the Stock #, Cartridge Caliber and Name, and whether a Rougher or Finisher is needed, with a 4-8 week delivery time.
The GILCHRIST PRECISION CHOKE REAMER is designed for precise cutter to bore alignment and can fine-tune choke size or remove chokes for screw-in installations.
It requires the Gilchrist Handle and two appropriate Clymer Choke Tooling Bushings for correct operation.
The reamer is available in different expansion ranges for 20 and 12 gauge shotguns, but pilots for 10 and 16 gauge are not available.
Gives the forcing cone a gentle taper to reduce recoil and improve shot patterns.
Spiral flutes ensure a chatter-free cut on all types of barrel steel.
Designed with a long shank for use with a large tap handle, facilitating alterations to most barrels.
