    From the recent MG shoot theres some brass from thompsons with what appears to be a slight bulge about 1/3 of the way up, and not all the way around. If its going to be sized and fired in a tight 1911 (not repetative bulge/size/bulge/size) will I be OK? Or should I steer way clear? Thanks!

    I have a bunch of military brass I shot out of department Thompsons, about 10% of them 'guppy' (bulge) during sizing, I just toss 'em.

    Its not bulging during sizing (well, I dont know yet, its bulged sitting as it is) and the brass is commercial stuff and norinco. Is it unsafe? Or just a PITA?

    A casepro or me are your friend. SMG’s can be hard on brass but they are still ok if you have the right stuff.

    I've loaded brass shot out of several different Thompsons, (all U.S. military rounds) and every one of the guns had loose chambers, so much so that a percentage of it takes two men and a small boy to size it. (Never really noticed any visible bulge before sizing but I have so much of it I don't really look.)

    Try sizing them, if you're going to have a problem it's with the brass being pushed down toward the case head and leaving a visible ring. Toss those, .45 brass is cheap and plentiful. If they size without problem or undue force they'll be fine. I should hundreds of 'em every week. .45 is a relatively low pressure round anyway, one of the easier rounds to load.

    Have no idea if Norinco is crimped or not, can't recall ever loading any.

    That machine is RAD with a capital "R". I've been getting along without one, but now I think I need one!
