Actually, you're the one who turned me onto it. Thanks!
Sorry... that group pictured above is a 200 gr Speer Hot Cor over 53 gr of RL-15 in RP 270 WCF cases sparked by CCI-200s. I have shown that group off extensively around here, but that rifle and load perform to that level regularly.
I spark my H380 w/ CCI-250s cuz I hunt in cold weather, the loads I'm running are VERY compressed, and I happen to have way more of those than the 200s and very few other reasons to run through them
.
The other sleeper powder in that cartridge is BLC-(2) which has yeilded incredible accruacy and speed through my rifle w/out signs of excessive pressure. IMR-4320, as other have stated, is well worth the effort, as is IMR-4064 though I have yet to try it.
Just got some SR-4759 to put under some 225 gr cast bullets I happened into for that rifle. Should be deadly 'yote medicine!
