I've shot over 1500 rounds of Remington Golden bulk packs, and had only maybe a handful of failures. That is a pretty good success rate for anything,
Your standards are really, really low. If I had even one failure in that many rounds of commercial centerfire ammo, I'd take notice. Two failures, and I'd start avoiding that cartridge. My standards for .22LR aren't any different, only I'd probably still buy questionable ammo for plinking, if it was the only thing in stock.
Here's my experience:
Fed Automatch : over 1500 rounds, one dud
Eley Club : 500 rounds, one dud
Fed 550 bulk pack : 1100 rounds, zero failures
Aguila Colibri: 500 rounds, zero failures
Winchester super X: 100 rounds, zero failures
CCI mini mag: 100 rounds, zero failures.
Remington GB bulk pack: 525 rounds, ~35 duds, and some FTF due to underpowered rounds. Hmm. 22LR catridges are small. I guess ~100 of them could be considered a handful?
It was probably a bad box. But unless it's the only thing on the shelf, I'll probably stick with the Federal in that price range. Having so many duds ruined the fun of even plinking. My friend and I ended up "disposing" of the majority of the box by loading them up with a speedloader and firing them off as fast as we could pull the trigger (and clear duds), aiming at nothing in particular.
