Beretta 22LR ammo question...

Try CCI copper plated. Lead ammo will most likely shave and jam.

I been away from .22 ammo for a while and am not sure but didn't CCI make a Mini mag copper round. If they still do it is a little hotter then regluar .22 rounds.

Yellow Jacket or any hypervelocity load....Using regular .22LR ammo is a crap-shoot for reliability, at least in my case with the 21A model...

Federal Game-Shok Ammunition 22 Long Rifle Hyper Velocity 31 Grain Plated Lead Hollow Points will reliably feed and will have higher muzzle velocity than standard 40 grain lead rounds.

IMO...
CCI Stingers only really reliable .22LR ammo for the Beretta Model 21A.

The only thing that I could get to run even half-way reliably through the one I had some time back was mini mags. Everything else was jamorama, and I mean everything. Beretta may have an extensive history of making successful and quality firearms, but they missed the boat with this design, IMO. Still, just because the one I once owned was problematic doesn't mean that yours will be. Good luck.

mine likes CCI Blazer ammo,try a few and see what happens. jwr

I've tried Winchester Super X and mine doesn't like it.

I only use CCI Stingers now and it functions flawlessly. If one doesn't go off, just pull the trigger again. (Part of the beauty of this piece is the double action.)

Oops, duplicate post.

I was able to get Mini-Mags and Stingers to work well in one I had, the other wasn't quite as picky. But they do seem to like high- and hyper-velocity rounds, although I was disappointed that Velocitors didn't work as well in the last one I had.

Federal Automatch bulk 40-gr RNL

The Federal and Eley primers seem to be the most reliable. All of these rounds functioned fine in mine, though. I keep the Automatch in it because they group well and I feel 40-grain solids are probably the best bet for adequate penetration (though I don't really see myself relying on this gun for defensive purposes).
