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.
