I use the .50 cal 245 grain Aerotip PB in my Omega and they work great! The deer I smacked this year with 'em took a few steps and collasped! I couldn't ask for any better performance. They also seem to shoot very accurately through my rifle. I'm printing just a hair high at 75 yards and my groups are outstandding, tighter than I ever thought I could shoot a Muzzleloader!
