Naive headspace question
« on: September 11, 2009, 04:57:06 PM »
If a rimmed cartridge is headspaced off the rim, and a rimless cartridge is headspaced off the shoulder, does that mean by definition there can be no such thing as a rimless straight-walled case, because there is nowhere to headspace off?

It is OK to have a chuckle at my expense.

Rimless straight-walled cases headspace off the case mouth.  .45ACP, 9mm, and more all headspace this way.

 Never mind, I found the answer to my question from Chuck Hawks.

Alright, I knew there was something I was missing, I usually do not think in terms of semi-auto pistol rounds. That's why...

'S OK, nobody knows it all (though some think they do!)  That's why we come here - to ask what we don't and answer what we do.
