I shoot 22lr ammo through my Beretta 87 (extended barrel version) and found the remington (walmart 500 box) to have about 2-3 duds every 50 to 100 rnds fired. Mini-mags have been 100% reliable for me. Stingers also are reliable but someone mentioned it might be a little hard on the beretta. Anybody else with recommendations? Reliability, accuracy, and cost???? thanks in advance.
