[QUOTE="22Kreedmire, post: 2592050, member: 107363"] I just built an origin SA. 26” Shilen 8 twist saami throat 57gr h1000. 140 eldm at 2.930oal (2.300ogive) Lapua brass. Fed 210’s. 3070fps. Went up to 58.5 with 143eldx’s and was 3144 and very warm. Lapua brass less capacity? Or fast barrel? Or both? Anyway. 56.5 h1000 143eldx was the best load with those and it was just over .5” at 100 at 3029 fps. 140eldm shot 2 groups .259” and .336” then straight to 300 it shot 1.61” cold bore was out a little next 4 were .79” group.
