Most manufacturers have quit playing those games. They generally (if you look) tell you what kind of weapon they were tested with, or barrel length failing that.

Doing a bit of googling, the .22LR doesn't gain much velocity beyond 14" barrel length, and loses less than 200fps from a 4" barrel vs the 14".

Well, given that .22LR out of a rifle length barrel is less than 200FPS above subsonic speeds, that kind of plays right into what he was saying.
