I'm sure that's close or right on the money, Jeff. I believe 37 grains of Lil Gun is max on the 335's but 35.5 puts them in one ragged hole at 50 yards using a Holosight with mine. I'll try them at 100 this weekend, but I don't shoot much with the healing shoulder these days. I shot 12 last weekend and that was enough. It's the off shoulder but they do let you know it wasn't a 223 in the rifle.
