Myself and some buddies are talking about getting into (or back into, in some cases!) reloading. Is there a powder, or powders that is most useful in loading more than one of the above cartridges, particularly safely or well for the gas operated AR, M1, M14?
Any crossovers with shotgun/rifle/pistol powders?
We were discussing stocking up with the most versitile components possible, for practice and hunting in lean times - like now. CC
