So I took my 15-22 out shooting today and had weird results.

Norma tactical subsonic cycled perfectly.

CCI standard velocity would fire, eject and fully chamber a round, but not reset the trigger. The chambered round had no firing pin indents. I thought the silencer may be the cause, but it did the same every round with or without. This ammo used to cycle 3 years ago.

Gun was clean and well lubed as normal.

The CCI ammo cycled fine in the 10/22, as did the NT.

Any thoughts?

Thanks
