[QUOTE="highdrum, post: 1960481, member: 13732"] My 26" proof sendero 1:10 was chambered with a 225 freebore reamer. 215 hybrids utilizing 215M primers, gunwerks(adg) brass and my particular lot of H1000 had pressure signs at 3100fpa. 3020 and 2970 had nice powder nodes that corresponded with great vertical impacts at 400y. I may have been able to squeeze a bit more velocity from it with a cooler primer like a cci250 or 210m. I'm not quite done developing this rifle however. If you look into what benrest guys have been doing, shooting 215s from 300wsm(same neck/shoulder as nosler) 225 freebore is the short standard. This keeps the bullet Shank above donut zone on case. In a saami throat, I'd run the 200.20x Berger. [/QUOTE]
