hillbilly, I have a 7mm rm with a 23" barrel. I have had 7rm's with 24 and 26" barrels also. In my experience velocity loss was less than 100 fps, and I could not tell a difference in muzzle blast. When I'm at the bench I use ear plugs and when I shoot game I never notice the sound of the shot, I don't see the big deal about muzzle blast from a 23" barrel, and don't think a 22" should make that much difference. I say cut it and with good handloads it will outrun any 280 rem. (which I have also had in 22"-26" barrels)
