I do agree, Ned, that it's best to use new ammo. I was answering the question, though, if it could be done.

Older stuff from the 40s and 50s is fun to shoot in Mausers and Hakims and Mosin Nagants, etc. But you sure have to clean them afterwards and there are lots of mis-fires and hang fires and squibs to be cautious with.

I have shot numerous old loads, even some from the 1890s, in my Krags just to see what happened. It's always interesting to test things out. But, as a regular exercise I do not do it. I save my old ammo, as in the picture above, for my Krag collection!

Keep safe!
