My dad picked up some 7x57 today. Should hear in the morning if it fit. He was planning to test fire it tonight too if he got the nod from the owner. It belongs to my aunt's husband. (I'd say uncle, but this is husband number xx...how many uncles can one aunt produce??)((nice guy, like him a lot though)). This rifle belonged to his dad and he wound up with it when his dad passed. He knew nothing about it, but wants to shoot it a little before it gets locked up again for a while. I don't think he's much into guns or shooting, but now he has one with a little sentimental value at least. Keep you posted. Thanks again for the replies.
