So I'm at the range shooting some new loads. I have a 16" 1x10 barrel. I have been using 190 smk's and 180 sst bullets with great luck. I loaded some 200 gr Nosler BT to be subsonic...when I fired them I saw a sparkle through the scope, I checked My buzzle break, No strike or anything else wrong for that matter. I fired four more rounds, each one sparkled down range. walked down to inspect target at 100yds. Five full keyhole bullet strikes!
so my ? is should I be able to stabilize a 200 gr projectile in that twist at subsonic vel. or should I just stick with 180 and 190 gr projectiles...i would be thankfull for anyhelp.
