Remington 760 after the shot....
I have a 760 that is 46 years old and in great shape. It is clean internally, locks up solidly, and without a jam. However, mine really likes to try and throw the casing out on it's own immediately after firing. Shooting off of the bench/sandbags yesterday with my hand under the pump, after the shot, the slide would move back almost 2" to the point where almost 3/4 of the casing can be seen. Is this normal? I understand it is probably well worn in from numerous cycles throughout 46 years, but I've shot rifles nearly as old that only opened maybe a 1/4" after the shot. The cases are extremely hot too so that tells me a lot of gas blowback is happening as the pressure drops in the chamber and barrel. My action is butter smooth, and I've handled 760's and 7600's that feel like someone threw a wad of gum onto the action tube and worked it in, so could the smoothness of the action just be the reason it wants to eject so effortlessly? I shot offhand and the same thing happens. I spoke to a gunsmith and he has said he has seen some do that too and it is more than likely just well-worn from age. It shoots great and everything like that and doesn't feel unsafe at all, I'm just wondering why it wants to open itself up rather than just unlocking after the shot. The first shot I took off of the sandbags, I had only the pump/forearm resting on the bags and the slide came back and the shell shot out like I had a semi-auto. Could it be a part that is too worn out perhaps? Maybe that pump ring that supposedly disintegrates after years and years? Just looking for input, the gun feels safe and all functionality is just fine, but what might be the problem?
