So with my current lack of reloading and hunting, i've been doing a considerable amount of reading on those subjects.
Was reading a article about belted mags, and my wheels got to turning. After a couple quick google searches and some wikipedia education it led me to a question about my 220 swift and headspace. Since the 220 swift is a archaic 'semi rimmed' case, does it headspace off of the shoulder like a 308 or does it headspace off the rim like a 303 Brit?
