We were at one of the many gunshows at the fairgrounds and there was a guy selling reloaded ammo out of his trunk in the parking lot. My buddy bought some, but I was like "you don't know what he put in there or if he even knows what he is doing." I don't think he has ever fired any of that stuff.
I have been hit in the face by a couple pieces of copper jacket at H&H, that was bad enough, I couldn't imagine a case exploding.
Yeah, I wouldn't shoot any reloads unless they were from someone I know pretty well. There are guys I trust to reload and then there's the guy selling out of his trunk...
