22 Magnum Winchester Super-X 40 Grain Varmint JHP X22MH - 50 Rounds

Bought this, along with several other brands to find out what works in my new Keltec PMR30. This ammo did not cycle the action well causing multiple Failure to Feeds and Failure to Ejects. Unreliable at best. Interesting though as I also bought 2 boxes of this same ammo in the FMJ Version and that ammo cycled just fine. There was a noticable difference in power between the two. Being that both this and the other item are exactly the same spec except JHP vs FMJ, I'm gonna lean to either this one being weak on charge, or the other one was a little hotter as a manufacturing inconsistency.
