I don't want to debate reloading, I know many have great results, I also know many are hesitant to share their failures when speaking of their experiences. I had one poor experience 30 years ago and decided then I had no reason to use them....until I got impatient having a new gun that I couldn't buy rounds for. At the time, I let the quality of the shop I was in give me confidence or an excuse to go against my better judgment. I'm a rather detail oriented individual, if I were reloading my own I'd probably feel completely different about it.
That makes sense, and I do understand the urge to go shoot a new gun with whatever ammo you can find. Obviously though you've discovered the danger of using someone's reloads of unknown quality.
I'm not against reloading; almost everything I shoot is reloads. I'm against shooting ammo that
someone else reloaded, unless you really trust their quality control. Even the commercial reloaders fall in that category for me.
