I picked up an interesting case the other day at the range. A 220 Swift, with the taper blown out, sharp shoulder, in 6.5MM. I've never run across one of these before, anybody know if it has a name? Neat looking thing for sure.
It wasn't mine, but I have a Swift based wildcat in the works. I've been fortunate to pick up a "used" fluted 23" 6 PPC Shilen benchrest barrels with a 1/14 twist. Ought to be a dandy varmit rig shooting 65 gr. VMax or 70 gr Ballistic tips. I have a 6PPC at the moment that shoots quite well, but locating brass for it can be a real pain.
I could punch it out to 243, but what fun would that be. So I decided that a 6mm wildcat based on the 220 swift would be a fun project. Well, that's been done in before, but I wanted to be able to do the projcet without custom dies or a custom reamer. Guess what, you can make a sweet little cartridge based on the 220 Swift case by short chambering a 240 weatherby reamer. I put a 240 Weatherby sizing die in a 7/8" collet and with a sharp carbide cutter, I made my wildcat sizing die.
Now all I need a 700 SA witha .473 bolt face and I'm in business.
