[QUOTE="steve smith, post: 21431, member: 110"] Pressures? I'm guestimating between 50-55Kpsi. Bulge in 404 brass? Yes, but it is not as big as I was lead to believe it would be. But then again just looking at the fired rum brass there is no noticable expansion ring. I measured some @.550" unfired and .552" fired. I believe the 404 base size is about .540, so .012" expansion, .006" per side is not as much as the 270win barrel that was originaly on this rifle. I'll sdouble check the numbers when my new set of dial calipers get here. The old pair I had crapped out on me yesterday. [/QUOTE]
