Question . When sizing 45ACP cases

cw308 · November 20, 2017, 03:47 PM

I'm sizing 45ACP cases with a RCBS Carbide die , the die is set up with the die touching the she'll holder without a can over. Cases are sizing fine , checked in a case gage . I backed out the die one an one half a turn , sizes the case half way down , enough to hold the hole bullet.The case checks fine in the case gage. Is this OK or am I missing something. I shoot bench rest 308 cal. I don't oversize , is it the same with a straight wall case.

Better to size it all the way, your concern here is reliability so full sizing for straight walled pistol cases is important to prevent a malfunction in a semi auto pistol. Unlike rifle reloading partial sizing will not make the case fit your chamber better nor is resizing going to wear the brass out.

I agree 100%. Plus a case gauge is good, but your chamber is better. The plunk test is infallible.

Some handgun cases are unsupported at the base (think Glock .40) and get a fairly good bulge at the base after firing... it's best to full-length resize all your straight-wall cases, and not even just in automatics. I have some .45 brass that's probably been loaded 20 times or more that I'm still loading without problems.
