I recently purchased a used Remington 788 carbine in 7-08. I gave it a good cleaning and noticed some odd hammer marks on the bolt handle. I looked closely and noticed no obvious defects, so I loaded up some jacketed 140 grain pills over .5 grain increments of IMR-3031. The first shot on the starting load locked the bolt up tight. When I tried to force the bolt up to unlock, the bolt handle ripped out of the bolt body and I cut the crud out of my hand on the sharp metal. Any idea why this may have happened? Will I mess anything up if I try to get the action open? Any bets on if Remington will even talk to me much less fix it? The gun shop I bought it from wont be open till Tuesday, and I haven't called Remington yet, so no new information there, but I really want to crack this thing open and find out ***, but don't want to ruin my chances of getting it fixed.
