Depends on the .22 LR rifle. My own .22 Ruger 10-22 loves Remington Yellow Jackets as-does my new (to me) Anchutz. both also shoot very well sub 1.5CM) at 50 meters with Winchester Super X HP's. Both rifles do better than this, with Ely match ammo.

Most rifles shoot well with Winchester Power Point .22 HP ammo. Browning ammo appears loaded with the Winchester Power Point HP, but is advertised at 1,450fps. It does not shoot as well in my rifles as-does Win. PP.

Every .22 LR rifle is it's own boss. You must try different ammo to find what YOUR rifle likes. Many .22 LR rifles have distinct preferences in ammo make and style.

This said, most .22 LR rifles prefer standard velocity match ammo over high velocity stuff.

I hope that translates with the program as I intended it.
