Sorry for double post. Would different grain wieghts effect the amount of flame cutting differently, or does a 125 grn flame cut the same as a 158 grn ? I recall something about the old Mdl 19's forcing cone cracking with extensive use of the high velocity 125 grn .357 Magnums back in the day, but being relatively fine with 158 grn projectiles. Something to that effect. My memory of it is shoddy.
