I just acquired a Remington 17, 20 GA shotgun. How durable are these and when were they manufactured. It was rusted and pitted on the exterior; on the barrel and reciever, but the internals looks great with not rust or pitting. and the barrel is mirror polish on the inside. It was stored in the garage and the barrel was pluged with paper and the reciever was caked in cosmoline. I guess the exterior of the gun was unprotected. In this condition, I know there is no collectors value, so I proceeded to remove the rust and reblue the gun. The design was very simple and the quality and workmanship is very good. Other than the blotched were there were pitting, the gun now doesn't look half bad. I plan on bringing it along on my coyote trip this weekend as a closer. The question at hand "Is 20 Ga OK for putting down game?" And is this gun safe to shoot, it looks strong and I don't think the pressure from a 20 GA is all that powerful? I like a second opinion though. Any and all info is appreciative.
