6BR won't shoot 105Amax bullet

Chris

The N140 shot quite well, but inmy opinion, not quite as well as the Reloader-15.

That barrel, for somereason, really liked reloader 15.

As a added note, one bullet it would not shioot that well was the Lapua Scenar 105, which is a beautiful bullet. I think the barrel, (a .237 4-groove), was a little loose for them, as all of the ones I had measured no bigger than .2427 any where on the shank.

Howerver, Ed's Rifle, which has a .236 6-groove Krieger, loves them.......jackie
 
I have shot a lot of modified 6br rounds in the last 10 years in comp. and also on ground hogs and have found that AA 2460, AA2520 abd Norma 203-B powders have shot the best in 4 different rifles. If the 105 A-Max doesn't get the job done(try hard in the lands and way off the lands before you give up on them) maybe the 87 gr V-Max might be better. Also the 450CCI primer might help.
 
back from load testing the 6BR today, found that the 105 Amaxs did their thing today 31 grs RL-15 450 primer, shot 4 touching and the 4th about 3/8 out, this looks good so far, excellent accuracy but the bolt has a little effort to lift it, can I try dropping 3 tenths of a grain, so the bolt will be easier to lift and not lose accuracy, made the load .010 longer from contact on the lands
