JHS; take my advice. Buy a large amount, say, 1000 rds. of new, primed, preferably nickel plated brass.
The difference in unprimed and primed brass is usually less than the cost of the primers.
All of your brass will be of the same lot, thus will perform uniformly.
You, of course, are aware that military brass is thicker than commercial brass, so powder charges must be lowered slightly for military brass. Also, military brass has the primers crimped in place. This crimp must be removed before reloading.
Brass also weakens with each use; perhaps not much, but new brass is strongest.
Don't be penny wise and pound foolish. Walt
PS I used to use GI brass in 30-06, would ream out the primer pocket, and put up with dirty brass, as I couldn't afford a tumbler (not a problem with Ni plated brass). Actually, I am not sure tumblers were available. I was 14 years old then. Walt
