Hey Quick (or anyone that knows) can a 414 Supermag clean up the 38-55 chamber? I think the 414 SM rim diameter might be a tad smaller than the 38-55 or maybe the other way around, can't remember for sure. Will check when I get home, but the thought hit me because I have a 3rd used 38-55 on the way, and I want to convert it to something. Thanks, Mike
