I'd rather 22" myself on the little FB. I got 3600 or more with Lil Gun and 40 grainers. Little thing flat shot.

Huntz, I bought a 77V Ruger 6mm years back BECAUSE it was chopped back to 21". LOUD as hell in that round, but shorter bbls are often more accurate. That gun had nothing else done and put 5 in ONE ragged hole at 100 yds. That along with being handier is reason enough for me.

Fireballs are quiet to begin with, and use such little powder, virtually meaningless loss in whatever velocity difference.
