Tech Tip: Shoot BR Cases with Rebated Rims in PPC Actions

Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30 BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6BRA, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.

To convert a PPC-boltface action to shoot the bigger cases you can spend a ton of money and buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. This is a relatively simple procedure with the right cutting tool.

Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30 BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.” At right is the lathe form tool Butch uses to rebate the case rims.
