[QUOTE="Trickymissfit, post: 438210, member: 25383"] I think I'd back the load off about .5 of a grain and see if that makes much difference, and then also seat the bullet about .003" off the lands. If things get even slightly better I'd back it off another .5 grain and seat the bullets within .0015" of the lands. Also change the primer to a Federal mag primer to help ignition while it's down one full grain of powder. I shot similar loads in a 6mm Remington, and the best it'd group was about .31" using the BTHP (I was using a 24" barrel with a 1:9.5 twist). The 20" barrel will want a little faster powder burn, so you might want to jump up one notch on the burn scale. Maybe H380 gary [/QUOTE]
