How many of these projects have been completed? Just curious...
Anyhow, why would you want to go with a scaled up .220 Swift? It's an archaic cartridge design, and there's much better geometry to be had if you're going from scratch. You'll get higher velocities from a shorter, fatter case of even slightly less volume than your scaled up Swift. All the .220 Swift is, is an overbore cartridge. The .50BMG is already overbore as it is, going down to .408, let alone lengthening it and blowing out the body at all, is just plain useless in my opinion...
That is unless you like buying powder by the 10lb jug and very expensive barrels several times a year.
How many guns do you own Dave? How much wildcatting have you done? I like others admire your enthusiasm, but I sincerely doubt this is going anywhere, just like the other proposed projects. Sorry to be a downer...
