Twopipe, a couple of years ago I saw in a local gunshop a Ruger M77 in what I believe was .300 Winchester Magnum absolutely destroyed. The floorplate had blown out, the trigger assembly was gone, the siderail was bent outwards and upwards, the bottom of the chamber had blown off, the stock was broken completely through, but the bolt had held. The owner claimed the rifle was defective. Yeah, right, the only defective was the owner who had obviously loaded a fast powder rather than the slow-burning one he claimed he loaded. I have heard that the owner of the gun shop refunded the guy's money and told him to never come into his shop again, that he was too stupid to be shooting.
