if it were me, and were thinking that everything had to be over 100 grains in weight, I think I'd ditch the idea of a six millimeter and head right into .257 Ackley territory. Or even better yet a 6.5/57 Ackley (same as the .257, but in a 6.5 bore). Bullets are better, and anything a six millimeter will do, a 6.5 will do better in spades.
