Hey guys,
I have a CZ 550 in 6.5x55 that I want to convert to 9x57 Mauser. Here's the catch, I don't want to re-barrel or set the barrel back at all. Hoping to just rebore and rechamber.
Would it be as simple as:
- Have JES Rebore/rerifle the barrel to .358 (so I can use standard 35 caliber bullets)
- Reaming the chamber out with a 9x57 reamer
Is that all it would take? I realize the rim diameter for the x57 case is a just a hair smaller than the x55 case... is that a huge problem? It's hard to tell if the 9x57 reamer would "clean up" the existing x55 chamber.
I know the simple solution is to re-barrel, but I'd prefer not to do that. Want to keep the gun as unchanged as possible.
Ps. If that won't work, is there a somewhat common 35 caliber wildcat based on the x55 case that I could use? Couldn't find one... but maybe it's out there. Thanks.
