This isn't on my shelf, but it is certainly in my memory, a guy at the range told me a "great" load for a 6.5 x 55 Swedish Mauser, well, I trusted him and I loaded up 20 rounds and went out and shot them and the first round went off much harder than it was supposed to, damn near like a 30 06, and I knew that that gun wasn't supposed to go off like that, so I came home and took them apart, and his charge was almost 3 grains over Max of what my loading manual said. Two lessons learned, never shoot anybody else's pet loads, and always, always consult the manuals.
