[QUOTE="BradinCO, post: 341827, member: 15175"] Thank you Mike for the tips. I've tried other primers to include Remington, CCI and Winchester but those loads have consistently been twice the size of the groups shot with the Feds. I attribute the velocity to the 26 1/2 inch barrel. The same loads chronographed out of a 24 in. tube give me in the high 3200s. Of course, I'm at 6000 ft. too. I work all my loads from the bottom up but this rifle seems to like them hot. I'm just on the verge of a sticky bolt but don't see any expansion of the primer pockets. In my 7mm Mag with the 168 gr. Berger VLD, I had good luck with 4350 but the pressures got too high just about the time it was starting to shoot good. I've tried 3 or 4 powders including H1000 and the best I've found for that rifle is Retumbo which gives me good accuracy (1 in. at 200) at 3040 fps. It is the only accurate load I've found that will break the 3000 fps. barrier. Best part is, no signs of pressure and it shoots GREAT! This rifle has a 24 in. barrel. It is an old '98 Mauser that I have speed locked, squared the bolt, lapped the lugs and put a Timney trigger adjusted to 1 lb.gun) [/QUOTE]
