Can I shoot 22 LR bullets in a Beretta 22 short caliber pistol?
No. The gun you are asking about is specifically chambered for the .22 Short only. My brother has one and that is all it’ll shoot. The link you provided is to the .25 acp Beretta. That one only shoots the .25 acp. I didn’t know Beretta was still making that model in .22 Short. And even hypothetically it will NOT shoot anything but the Shorts as the Long and Long Rifle are too long and develop too much pressure for the aluminum alloy frame it is built on. If you want something more powerful in similiar size check out the Beretta Model 3032 in .32 acp. This one is a double-action and still has the tip up barrel.
