[QUOTE="osok-1k, post: 2427867, member: 106259"] I'll be interested to see how the new Hornady CX performs, replacing their GMX. If you could find some it might be worth a try. Although, reading the expansion levels of Barnes posted by choprzul, the CX will require higher velocity to reliably expand, according to Hornady specs the 30 cal 165 has partial expansion at 2000, less that double bullet diameter. Higher velocities perform much better. A large bull elk would be a good test as it appears that penetration should be good at any velocity above 2000 but depending on range you might have to have something faster than a 308. I think 165 is the lightest 30 cal CX with moderate BC .440. The 190 is CX is .575 which would be great in a PRC or win mag. Smaller caliber CX BC's are not impressive as the line is pretty light in weight for caliber. Example .270 only goes to 130, .403 BC [/QUOTE]
