[QUOTE="Orange Dust, post: 2234500, member: 92702"] Ok, I guess I'm going to put a theory out there where it is "possible" that fouling was the problem. Not the copper in the bore, don't believe that for a minute. Dreaded Carbon ring? that will increase pressure for sure. It is possible for a burned throat to hold enough fouling to push the bullet back in the case, and way back if chambered hard and a low powder fill. This can easily cause a frozen bolt, and possibly a deeply fluted barrel could let go too. All possible. Likely is an obstruction a couple of inches in front of the bullet. I have also seen bullets separate from jackets in heavy magnum revolvers with a rough throat. I've never witnessed it with a rifle, but it is possible with enough fouling, and possibly helped along with a double pressure spike. Part or all of the jacket from the first shot remaining in the barrel would account for the great copper coating on the barrel, as would an oversize bullet. The bullet stripping its jacket on the first shot would line up with the evidence in the pictures, but I've never seen it happen with a rifle. [/QUOTE]
