Does anyone remember the Remington 5 mm? I had a bolt action, 5 rd. mag. It was the most accurate rifle I have ever shot. It did a number on any groundhog that I happened to see. However, mine kept blowing up, bursting the case, usually blowing the whole rear off the rest of the brass. This would explode the plastic mag. I sent it back to Remington 5 times to be "repaired", but it blew up a sixth time. That was the last straw, and I traded it for a Remington 700 in 22-250. I still miss the 5 mm.
