I have loaded up some of beartooths 200gr wfngc bullets at 1.26" and they hit the rifling far before fully chambering, I had to shorten them to 1.22" to get them to chamber. I e-mailed kkm and ask if they could ream the chamber and open it up for the Beartooth Bullets. The answer was" we cut our chambers to SAMMI specs". So, do you guys know any where to send my KKM barrel to open it up enough to be able to use the Beartooths I have? I guess I can use the facxtory barrel with these and they will chamber fine but its kinda messed up to buy a new barrel and have ammo fail to chamber fully. james Wanna kill these ads? We can help!
