I never heard of a "primer round .22"
And I am a Hunter and gun enthusiast...
U can get "birdshot" rounds...
Sub-sonic .22's...FEDERAL
But if you want to use those weird azz
Rounds you better get a single shot bolt action
With a 5 shot clip...
Old savages, Sears, H&R, Remington,
Go to an estate sale or flea market....
THE BEST .22 ever is the RUGER 10/22
Semi-automatic. With the 10 shot round barrel clip but it won't work with
Subsonic or BIRD shot...
It may? Work with .22 shorts....??
Use hollowpoints....
Or if noise is no problem CCI STINGERS or
CCI VELOCITERS...HOT HIGH POWER 1660+ fps
and they are hollowpoints...
Winchester Wildcats always work good and basic federal .22's are good....
A company out of Mexico ..name? Makes many different types of .22 ammo (?? Arguilla?)
