At my local WalMarts I can't find the 550 pack of Remington Golden Bullets anymore, now they have the 225 packs for 10 bucks. The 225 pack says "New and Improved" and I believe it. I've now gone through 2 boxes of the stuff over the last 2 outings (1 whole box per outing) and I didn't have a single failure of any kind with this stuff over all 550 rounds. I could not say the same about the 550 backs of RemGB that I've used before. I would usually get 4 or 5 duds, between 5 and 20 failures to eject and/or feed per 550 pack. It wouldn't happen ALL the time, but it was just often enough to be distracting (after every shot I would think about whether or not it would go bang again). Anyway, if you have an AA kit and haven't been impressed with the 550 RemGB packs of the past, I recommend you pick up a new 225 pack and see if it works any better for you.
