18" seems to be the optimum length for .22LR barrels. After that, the longer barrels cause fricton slowing the bullet down.
For centerfire rifles, somewhere in the 32" length seems to be the maximum length before frictions sets in.
Have absolutely no idea how this works for shotguns and muzzlestuffers.
I'm going by faulty memory and what has been read in various trade publications, so hopefully, there's someone out there with actual ballistic knowledge to verify or refute these findings.
