#4 bolt heads

[CINDERS]

I got what x85 was on about but shooting a weapon when the cases continually split would have me looking seriously at the headspace or the chamber is grossly O-sized if he is using factory loaded ammo then it could possibly be said the rifle may have headspace/chamber issues but if reloading his own ammo for all we know he could be using 45grains of AR 2206H behind a 215gn Woodleigh projie with a CCI-215M primer !

Could the finish be covering up the US property !
Anyway there are far smarter people here to answer or extrapolate the issues for x85
