[QUOTE="Rexby4, post: 1992927, member: 114488"] I have similar pressure issues with my CA Mesa in 6.5 PRC. It sounds like your chamber is too tight. You may need to get it re-reamed. SAMMI SPEC for head space is 1.6517 -.007 = min 1.6447 Your fired cases are only .002 off the min. New unfired Hornady brass is 1.6420, New unfired ADG brass is 1.6430. And I measured unfired Hornady Precision Hunter 143 eld-x and got 1.6440. My average fired round measures 1.650, I’ve seen 1.6515 The two thing that have helped me is, I full length my cases to 1.6435 (I’ve stopped trying to just bump the shoulders back) and I trim my cases to a max of 2.02 I also like using H-1000, but have see impressive accuracy with VV N565 [/QUOTE]
