[QUOTE="dworrel, post: 2587281, member: 15241"] I’m hoping to revive this thread. My build: Tikka T3X action Mesa precision stock Mountain Tactical DBM that fits Tikka inlet CF wrapped 26” barrel from Preferred Barrel Blanks in 25 Sherman Vortex Razor LHT 4.5-22 I found some Nosler 270 brass and fire formed. I did a ladder pressure test with VV N565 which was interesting... I started at 56gr in 1gr increments up to 60gr, then 0.5gr. I had no pressure signs until 62gr, then blown primer which I thought was odd given no primer flattening, no ejector marks, no heavy bolt lift. I cleaned thoroughly, did another pressure test today with VV N570 and went from 56gr - 64gr. I had an ejector mark at 64gr. I’m going to do further load testing this weekend. We’ll see… [/QUOTE]
