44 AMP the bore diameter is 264.5 at the muzzle on my hornaday digital caliper.But i did buy some graf and sons 6.5 ammo for it when i picked up the stock.I will have all the parts for the rifle by tormorrow to send it to a gunsmith for head space checks and a final once over before heading to a range. but i do know about the gas blow back cause my type 99 does the same thing but i have cleaned the chamber out well and it stop but there still gas blow back from the gas vent holes on the top.
