I'm looking to order a Lee mold for my AR10's and 700P. Now my 49th edition Lyman reloading manual gives 7 different cast weights including... 115, 160,170, 173, 180, 190, and 200. Lee makes a mold for 160, 170, 180, and 200 so those 4 are my choices. If looking at a bullet for whitetail deer, black bear, defense, and distance target shooting, what is going to be all around the most versatile in regard to weight? Also, all of the loads call for a gas check. However, I powder coat all my cast bullets. Can I get away without a gas check?
Thanks!
