Gotta have the right tool for the job.
The size is pretty consistent. .689-.690
I shoot my Jacko Infinity, CP .689, and a J&J Ceramic with Kick'n Metallix and sometimes Premium Plus.
Your boomstick (if it isn't a custom size) would probably be too tight.
My team has been shooting Kick'n paint since Feb with no hassles.
A few weeks back I shot three cases at a tourney in MS. No chops or barrel breaks. I removed a lot of players (2+ per game). I think bounces were minimal.
Stick with Metallix for tourney players. Premium Plus is very good (that MS tourney had P+ for the Field Paint) but Metallix is their top of the line.
