Has anyone used bob cauterucio bullets for hunting? What kind of performance would you expect on an elk shoulder shot? The bc on their 189 gr is reported at .8+. Looking for an elk bullet, kreiger 26" barrel, 1:9 twist.7mm stw, w excellent long range performance 1k? The berger 180 vld .659 bc or berger hybrid .674.bc look like tried n true options. Additionally would like advice on a second lead free elk load. Looks like a conventional pick would be the banes 168 lrx bc .55. Cutting edge bullets has an all copper 170gr at .610+bc. Any advice would be greatly appreciated.
