A couple of years ago, I had one of the now rare S&W 15-22 pistols, a fun little toy, and the Golden Bullets were one of the ones S&W recommended not be used in it. A friend of mine bought one too, and the first time I shot it, we shot what I had, a couple of boxes of Federal 36gr copper plated stuff that worked perfectly. We put a bunch of rounds through them with one misfire that was too weak to cycle the action in my gun. The second time we shot them, my friend had bought one of the GB buckets of 1400(?), and we figured the worst that could happen was we would have a lot of misfires and some feeding issues, but it really didn't happen, we each had a couple of misfires and a few more that we tossed while loading the mags, but probably 98% of it was fine. I sold my 15-22, but my friend still has his, and a couple of other semiauto pistols and rifles and has shot GB in them several times. It's not the best stuff, but it doesn't seem as bad as it used to be, or was claimed to be.
