I think I’ll do an experiment:
With hyper-velocity .22 lr ammo like CCI’s Stinger, I’ll shoot one shot thru a suppressed Ruger 10/22 with a 22” barrel, then move the can over to a 5” barreled Browning Buck Mark, and shoot the same Stinger ammo.
I’ll need to take a couple fouling shots first, to take away “first round pop”.
Or, let BOTH guns do one shot thru a cold can, with fresh air in it, so both shots will have some FRP.
Will the Stingers stay supersonic out of the 5" barrel?
