I had a venture I sent back 3 times for misfiring. It was chambered in 280 rem. The second time I got it back it had a magnum bolt in it. The customer service guy thought I was an idiot when I told him it wouldn't eject the shells beacuse it had a magnum bolt in it. He just wanted to know if it would fire or not. The third time I got it back it found a new home. I don't even remember if I tested it or not.
