Depends on the rifle - most .22 rifles I have shot the Colibri from worked fine - only the Winchester 75T target rifle had a tight bore that caused a 'stickage'.
I did get a brick of Super Colibri afterwards.
I find the older 'vintage' rifles tend to shoot them better, and the same when using the Aguila 'SSS'rounds - different rifling rateI would guess. They work great from my Romanian M69.
The 'SSS" was also the only ammo that would work in my Whitney Wolverine pistol when I first got it - some TLC on the chamber face fixed that.
The Colibri and Super Colibri (350FPS and 550FPS respectively) are distance limited - about 25 yards is max, and there ain't much whack factor then. I once bounced a Colibri off the skull of a home-invading Possum at point blank range - found him dead later but he shook it off and ran - it wasn't a clean kill.
The "SSS" has excellent "Whompability" (coined by a shooting buddy) on small critters. But the rifle has to like it to get good accuracy. It's not as quiet as you'd think either, but it has no 'CRACK!" like most .22LR ammo.
I need QUIET too. Tried popping a squirrel once with my Red Ryder - ewww..... did he ever curse me out! Haven't heard language like that since my Navy days.
