WCC brass, TB @ 8.8, 150gr. Winchester soft point round nose flat base 30-30 boolits and Win LR primers. Runs fine at 20' elevation, 35-70 deg. Remember, the SPR sports a 24" tube, maybe thats why theyre flyin straight. Theyre hitting on the nose at 185 yds. I went down and picked up about 5 nicely mushroomed projectiles from around the target, and numerous deformed pieces of 30cal lead and mangled copper jackets as well.
Ive loaded some 175 SMKs. haven tested them past 50 yards but theyre good at that range. Ive loaded quite a bit of subs and never had a baffle strike.
