A couple years ago I bought 250 rounds of 357M (158gr) ammo from a commercial reloader I'm not willing to name just yet. At the time I was too busy to reload, so I just bought some. A couple weeks ago my wife and I were at the range shooting some of it for the first time. I had noticed that the recoil/flash that seemed really inconsistent, and then later my wife called me over with a jammed gun. It seems a bullet had lodged across the forcing cone and locked it up. I pushed the bullet out and packed up the ammo for teardown. I was hoping to do that this weekend, but I ordered the wrong brand pulling collet. I was still curious so I took a few apart with my inertia puller. Most of the rounds had a powder that most closely resembled ash and had roughly 12.9 to 13.6 grains of that. The others had a flake powder and the variation was 4.4 to to 4.9 grains. I understand the reloader using the powder that was available (I bought the ammo in 2103) so there can be two different kinds of powder, but the variation struck me as really odd, rendered unacceptable by the squib load. Should I write this off as the results of a bad year, or should I avoid buying from them again? I sent them an email about it after I condemned the ammo, but never heard back. Thoughts?
