[QUOTE="bigedp51, post: 1179283, member: 28965"] I have read many post where someone said too short of headspace will increase chamber pressure. Military headspace for the .303 Enfield rifle is .064 minimum and .074 maximum. My No.4 Mk2 has had the headspace set from .058 to .084 and this never had anything to do with changing chamber pressure. The only effect it had was on how far the case would stretch when fired. So how would tight headspace effect chamber pressure when neck sized only cases become tighter fitting to the chamber dimensions each time they are fired. And when setting the headspace to .058 the bolt face was just barely kissing the rear of the case on the Enfield below. I know I heard it before, so don't tell me I should not have played with my bolt head until I nearly went blind. :D [IMG]http://i122.photobucket.com/albums/o254/bigedp51/IMGP1355-1_zpsptjasgxm.jpg[/IMG] [/QUOTE]
