I will have to get some m2 ball. I don't have any right now and it's gettin hard to let the thing set. but,I also have a 1917 and hopefully in the future 1903 both of which I'm under the impression are ok to fire modern stuff. I would like to have them all three able to shoot it to avoid any confusion. and make ammo easy to get off the shelf if I need. Or where can I find all the info to reload my own to military spec so that can be the only thing I need to keep around. I have been reloading for about 2 years and my manuals don't give me that info.
