I have several bags of 6mm brass and was wondering if I can run it through my full length 243 die and trim to length. Would it work in my 243 win.All brass is new never fired Thanks for your help.

I took one of my scrap 6mm Rem cases and sized it in a 243 and no it wouldn't work. The case body on the 6mm case would be 0.10 smaller than the 243 and you would have a lot of trimming on the neck to get it to 243 length.
