Duds galore - Browning BPR Performance 22 Long Rifle 36 Grain Hollow Point Rimfire Ammunition

Unfortunately, I purchased two 400 round boxes. Never have I experienced so many misfires. I shoot Winchester, Remington, Blazer, and Aguila with virtually none, so I know it is the ammo and not my rifle. If it were a bolt action, it wouldn't be so inconvenient, but with a semi-auto it puts a real kink in my rapid fire drills! For the sake of others, I hope this is just a couple of bad lots and not a consistent product defect.
