[QUOTE="cornchuck, post: 2863630, member: 20220"] I have been working up some loads for my Christensen Arms Mesa 300 PRC with a 1:8 twist barrel. I think I have found something that might work. Barnes 200 LRX with H1000. I had been doing a slight different version of a OCW test. I start my testing almost at minimum, 70.0 grs., and work up in .5 gr. to 75.5. At 75.5, I could hear some crunching as I was seating the bullet. Barnes says min is 69.4 (2644fps) and max is 77.1(2891 fps). I loaded these at book length which is 3.500". Which is about .10" shorter from mag length. Take a look at the attached target. I think I know which load I want to work on. Just want some opinions on what you see. Plus, I'm wondering if it's fast enough for what I am shooting. I haven't ran these through my Magnetospeed so don't know how fast they are. Usually find that after I find a load.
