I'm canneluring all my bullets that I'm loading for .400 Cor-Bon. Just got in 1000 rounds of West Coast Bullets plated, 160gr., fprn. I'm canneluring pretty deeply, and haven't poked through the plating yet. Seems to be really quality stuff. Accuracy is great. I'm using a compensated Accu-match barrel in a G21. I've clocked the 160's pushed by 10gr. of AA#5, at 1250fps, with no problems. Cost, $56, delivered.
Shoot to kill; they'll stop when they're dead!
