I have played with all of the 22lr ammo out there. Everything from the colibri to shot shell to the hyper speed to the target ammo
I also did not like the colibri out of my rifles and they get stuck under the fronf sight of my CZ. Works great out of a revolver, killed many a mouse and rat with them.
For back yard pest control I went to CB longs, you just need to watch your back ground. They function better in my bolt rifles. I even built a rifle just for them. Call it CDG
Click Ding giggle.
All you hear is the click of the striker, ding of the target, it's louder than the Colibri by far, and everyone who shoots it at steel giggles.
I can get the 60 grain rounds to shoot out of one of my 10/22's as well as my TPH pistol.
But as the gentleman above said what do you want the ammo to do?
I used to hunt with the stingers, thinking that speed kills, and all they did was make a mess of the game and made it so I had to shoot everything in the head.
I found that the 36 or 40 grain standard ammo works really well on everything up to Coyote out to 60 yards.
If you are looking to go past that....
Go to 22Mag/75 yards, 17 HMR /100 yards, or 22Hornet/125yards. Anything past that I'd go 223 or more.
I am going to try to post pictures of my rimfire guns as well as CDG.
