I believe the article you are thinking of is; "Mystery Solved," Charles E. Petty, Handloader 187, June-July 1997. This was about PMC and their experiences blowing up a 6.5 X 55 rifle and then blowing the same barrel off their pressure gun. I wrote Dave Scovill about this article and told him I thought it was the article of the decade. Dave wrote back, nice fellow, but I don�t recall what he said.
