Have a Thompson center in 375 Winchester and need brass. Have read different ideas about using 30-30 brass and fire forming it but without more info I will stick with something that is safe. So if anyone has any 375 Winchester brass I would appreciate some help.

Back in the day my father and I turned 375 win brass into 30-30's for tc contender pistols. I don't see why you couldn't reverse it. The case head on the 30-30 is supposed to be a bit lighter duty than the 375 win, but loading a bit easy on it would take care of that. After necking up there may be a bit of hour-glass shape, but pulling the trigger after you load it will cure that.
