At that low of a powder charge, don't overlook the pure lead, not jacketed, precision rifle dead center bullets. I previously tried the hornady xtp 300 grain bullets and the jacketed hollow points that remington marketed a few years back in the 303 grain variety. They all shot great but for some reason ( I expect the velocity wasn't great enough) I couldn't find a deer for the life of me. I was ready to hang up muzzleloader hunting until the precision rifle bullets were suggested. They were the answer to my prayers. At 5'7" and 240 pounds, I shoot a 220 grain bullet and 80 grains of 777 powder. They do not kick the fire out of you and they are extremely accurate and they expand really well and have incredible knock down power. Check out the thread about bullet expansion and see what I'm talking about. Good luck ,Greg
