Chambering your barrel with any caliber you choose.
Crowning your barrel with a recessed crown Barrel Crown.
Our chamber reamers are treated like gold as each one is ground to meet critical dimensions. As a result, your polished chamber is dimensionally correct. This allows for longer case life as your brass will not expand as far as it would with a loose chamber.
All chambers are polished and free of tool marks, thus minimizing friction between both the brass and chamber, and more importantly, the bullet and lead angle. We have an extensive inventory of chamber reamers. If we do not have the cartridge you are looking for, we would be glad to make arrangements to acquire it.
Note: If you plan on supplying your own chamber reamer: It is subject to our inspection and approval prior to use and we reserve the
right of refusal. Unless we supply the reamer, we will not be responsible for its condition. Any repairs or modifications we make to your reamer will be your financial responsibility. Unless otherwise stated, we require you to supply a head space gage and reamer print.
The actual crown is cut 45 degrees to the center line of the bore and is highly polished. It is also recessed to protect from possible impact.
