Never knew about pin gauges! Duh! Retired from body work. So being Polish, I pounded a bullet thru the cylinder of 2 guns and got a .451 reading. As I was setting up the Dillon 550 for 180 gr SWC I seated one of the DEWC’s in a case. Got one of the revolvers out and it would not chamber. Guess resizing is in the future.

I doubt if any will be loaded flush with the case mouth, afraid of high pressure even with the hollow base. Thanks for the offer 4barrel, loading HBWC in .32 & .38 and want to shoot them in .45 acp also. Larry
