Well...

I purchased this rifle a good while ago. Someone did not treat it too well I'm afraid, putting a ridiculous butt extension and drilling the side rail for a side scope mount (sans the mount). I took it apart and cleaned out the grime and dried oil, grease, etc. I installed a proper recoil bad (the stock is too short for anything else I'm afraid). Based on the maker's marks, I feel that this was made by Krieghoff. It's a beautiful little gun however, and I paid very little for it. I think it goes without saying, but I really do like it.

This is the embarassing part...

It was sold to me as an "8x57". I wasn't sure of the bore size (IS vs I bore), so when I did my initial chamber cast that was my main focus. The bore measures out at .321". So following the advice I have read here and other places, I decided to buy some light loaded US made 8x57, fire a few of those, and see if a standard .323" bullet would fit into the fired case. Well, it did. However, I noticed the primers were slightly bulged. I then looked at the necks, which were stretched somewhat. My first thought was excessive headspacing, but I felt that it would be odd that this rifle, which is completely serialized the same, would have excessive headspace. Although that is certainly still a possibility I suppose, another thought struck me. 8x60? Well I suppose that I'm lucky nothing bad happened while firing the rifle, but I thought I would put this out to the experts. What do you think? Here are a LOT of pictures. Additionally, I have some 8x60 coming in the mail.
