id look strongly at the hornady sst in 250 grain. i get excellent groups out of my omega with 100 gr pyrodex pellets, about 1" groups at 100 yards. I havent killed anything with them yet, but everybody ive heard of says they are awesome and many deer drop in their tracks. Ive heard they give excellent blood trails and pass throughs too, and I just cant wait to try them out next fall.
