I've had 2 very early Rem 700's that old lubricant had hardened so much that the trigger was slow to reset under the sear when you released it, and one sort of related because the weight spring was backed out too far. I like the firing pin safeties, but they are just as bad about dropping the firing pin if you don't have enough sear engagement. One additional test that I do is to cock the rifle, put it on safe, and rap the butt straight down several times pretty hard on my work table, then snap it off safe and do it again several times. If it drops the pin at any point, I add engagement until it won't.
old family, thanks for the link.
James, it couldn't have been a .22 long rifle could it? Had to be a .340.
