[QUOTE="benchracer, post: 1238971, member: 22069"] I think Buttermilk's explanation is an accurate one. I would add that powder composition has a role to play, as well. Awhile back I was working up a load for my son's .243, shooting a 95 SST from a 22" barrel. RL-22 was blowing fireballs with every shot, which surprised me a bit. I had used it with excellent results from my 7x57 (also with a 22" barrel), using 160's and 168's. The more overbore nature of the .243 changed the equation, though. I switched to H4831, which has a pretty comparable burn rate to RL-22, and the fireballs went away. I suspect the difference had more to do with RL-22 being a double base powder. [/QUOTE]
