Mostly duds - Browning BPR Performance 22 Long Rifle 36 Grain Hollow Point Rimfire Ammunition

I have a Cooey 64B with a strong ejector spring so I need high velocity ammo just so it would cycle the rounds. I bought 4 boxes of browningBPR because the ballistics looked good. First box at the indoor range I tried 6 rounds and none of them fired! I had some Winchester ammo with me and they worked in the semi auto 64B. The 6 dud Browning rounds worked in my bolt action rifle though. The semi auto made nicks in the rim but they would not fire in that rifle which tells me that there is a design flaw somewhere on the rims of the ammo.
