Yes! The Remington Golden Bullet hollow points jammed at least once per magazine. The CCI Mini Mags are great. Also, stay away from the CCI Low Velocity .22LR. They don't eject at all due to the reduction in pressure. The bolt doesn't go all the way back and you get the stove pipe effect. Shell half in and half out, with the next round trying to load. It's a mess.Best: Federal 550 bulk pack from Wal-mart or CCI Mini-Mag.
Worst: Winchester 'Expert' bulk pack and Remington 'Golden Bullet' bulk pack.
