So why not just have a local, say perhaps in the Sun Prairie/Token Creek area, just fire up the Dillon 550 and provide .45 ACP for a hell of a lot cheaper?
I never reloaded for my Thompson. Ever.
The idea of a squib load is pretty scarey when shooting full-auto.
Besides, who's going to take the time to do all the reloading?
And why should someone take all that time? This is a fund-raiser. People should expect to spend money.
