[QUOTE="284STW, post: 133947, member: 7010"] Win Mod 70 classic stainless, McMillain Lazzeroni Sporter stock, Factory 26" barrel (re-crowned), 82 gr Retumbo, W-W cases, 3.598 OAL, Fed GM215M primers. I consider this my max load. Last .5 Grains spike the velocity pretty good. Bolt still lifts easy and the primers look about par (flows around the pin with everything I feed it) I used a shooting chrony approximately 12' from the muzzle. Any closer with that rifle and I don't get consistant readings. I have noticed out of three different factory 7's that I've been messing with (2 Win STW's, 1 RUM Rem 700) mine has the "loosest" barrel. I'd approach that load with caution of course. By the way, does anyone know if the Fed GM215M primers are colder/hotter than the others. With the other STW I loaded 88gr H50BMG w/ 160 Nosler Accubonds with pretty good accuracy. It's a Model 70 LRH 26" bbl. I noticed the following: CCI Magnum Rifle Primers ~1/2" groups @ 3050 Fed GM215M Primers ~1 1/4" Groups @ 2930 The loads I've developed for mine love the match primers, basically every load I've ever developed for it. My buddies STW seems to think different, gotta love it... [/QUOTE]
