Howard, I have shot federal punch 22lr ammo before just not out of a bersa. It's worked great in several other firearms like a Marlin model 60, my picky Walther p22 and gsg Firefly, heritage rough rider, and Ruger sr22. Functioned fine in all those, so you should have no issues. I'd recommend buying a box and if they work great stock up, if not you know better next time. Hope this helps.

Howard, ironic that you ask. Just received a box from Norma on top of some 357 Mag ammo just to try. I don't have a Bersa, but it works wonderful in mt Taurus TX-22, Ruger LCP II & SR-22. I was actually impressed with the performance. Get a box to test and it it works out, stock up. Cheers and stay safe!
