Colibri sticks in the barrel on any of my rifles. It will shoot though a revolver. I like the CB Shorts but they will not cycle in the 1022 and the Quiet Semi-Auto will with a ME of 70 FPE which is nearly three times that of a magnum break barrel .25 caliber air rifle, typically more like 25 plus or minus FPE. Of course, if noise is not the only factor but legality of a firearm, then that niche can be occupied by several air rifles. My Steroid 392 (.22 caliber pumper) gets over the 20 FPE hump quite nicely and unlike the .25 magnum gas spring gun I have, it is very accurate at 25 yards:
I am under 25 yards, maximum 30 yards, with all of this Quiet ammo and/or air rifles and what not foolishness. Out past 25 yards, as long as a powder burner is legal, there are better choices and better ammo. That said, the segmented bullets dump all of their energy instantly, I would not want to get hit by one, it is gonna leave a mark!
