Some can't kill deer with a PB. Others can do better.
The wife drew a muzzleloader cow tag for CO this year. I've always shot the T/C Shockwave out of my CVA Accura II, but as you all know they aren't legal in CO. So I tried the Aerolites. WOW! The 250 grain Aerolite with 100 grains of Blackhorn 209 powder shot consistent 2" groups at 100 yards with open sights. The first afternoon of her elk hunt she took a nice cow at 90 yards. The cow went about 30 yards after the shot leaving a massive blood trail. Good job PowerBelt!
