Home Forums Hunting & Shooting Handguns 22 LR HP expansion in 4 - 5.5" barrels

Try shooting into a water-filled milk jug to see if you're getting any expansion. 3.5" barrel velocity isnt going to be great.

I've tried a number of different brands of ammo and only the really hot stuff will expand moderately from a 6" barrel (chrono'd well over 1000fps).

See the following for some velocities:
