[QUOTE="Engineering101, post: 1163933, member: 63138"] John I just got a new 22-250 barrel. It is a 28 inch 8 twist Brux. I stuck the barrel on one of my Savage model 12s. I threw some powder in a case just to check burn rate and put some 80 grain Match Kings on top. I fired 3 shots at 200 yards and they grouped 0.172" including the clean cold bore shot. Velocity averaged 2,920 fps and ES of the last two was 4 fps so there is some potential there. The load was 36.0 grains of H4831SC with the bullet seated 0.005" off the lands. I've got 5 more loaded for another trip to the range. I won't bother with a ladder test if they keep shooting better than I can shoot as the velocity (and thus the pressure) should be easy on brass. Take a look at H4831SC. [/QUOTE]
