.........I bought this out of an add in the Shotgun News many years ago and it came from upstate New York. It had an old OLD straight tube Leupold scope on it. It had a post and wire rectical and was a fixed low magnification. The scope's in a box in the shop or I'd go check . It doesn't have any adjustment knobs for windage and elevation. Instead it has 2 rings back by the eyepiece. I think the tube is brass as there are a couple places worn in the crinkle black paint that show brass.
There is still some color casehardening here and there in protected places on the lever, the bolt, trigger, hammer, and upper and lower tangs. The bore is sharp and clean. It had obviously been used, as most all the finish at the front of the reciever is worn where a person would wrap their hand around it. The wood is in excellent condition. It was well cared for.
The groove is .379" but it will take a .381" slug seated in the case so that's what I size'm too. My favorite load in it is the 225gr tapered Saeco FNPB with a cardwad over 16.0 grs of 2400. It's a fine shooting rifle, and one of the nicer ones I own.
