Went to the range yesterday and ran into problems immediately. I chambered the round, not really paying much attention to it since it has never happened before, and didnt realize the round wasnt fully seated. Pulled the trigger and noticed a lot of smoke. I noticed the next few rounds werent working either. So then I switched to some high dollar hornady ammo and that seemed to work well enough. No issues there. Then I switched back to the reloads, and checked each time. There were several times where the bolt looked fully engaged, and the round would not extract after firing, I would have to manually pull the bolt to extract it. The last straw was when a round became completely jammed after firing and I had to use some serious force to pull the charging handle back to extract it. The rounds would like the those pictured below. I bought the reloads at a gun show from a reputable vendor, which I wont name here since I plan to contact them directly. From what I can tell it appears that several of the cases werent sized correctly, does that seem right to you guys? I am kinda bummed since this is essentially a brand new 500 rnd pack and I cant really use it. Before this ammo I had put about 200rnds of factory ammo through it with no issues so its either the ammo I just got or the extractor is messed up, which is known to happen on these rifles.. Either way do you guys think I have hurt the rifle by these couple of rounds that have not fully seated being fired?
