.264 reloading issue - 11/10/15 10:19 PM
Helping a friend reload .264 Winchester magnum. Issue we are having is when round goes into chamber projectile is pushed deeper into case thus making round 1/8" shorter. Bolt will not lock in. After measuring everything we came up with projectile being to large in diameter. Factory round projectile is.257" in diameter. Found new projectiles (Sierra 6.5mm 140 grain) suggested by Lyman reloading manual to be .263" in diameter, barrel measures .263" also. Could this be an age issue(gun is 30 plus years old) and has anyone come across this issue with any caliber? Any help would be appreciated. Regards, Zane Powell
