Re: 6mm/220 swift?
I had a 6mm CJ which is necked down to .224, back 20 years ago bullet selection was junk and it did take some extra reloading steps neck trimming etc.. once you get up to 4000 fps it would key hole bullets all day, she was fun to shoot and I shoot a heck of a alot of fox, coyote, etc... back when they where worth $100 to $150. I was always into hotrod guns thats my log in. I set the barrel back 3 times than sold it. It was a ruger varmit heavy barrel and shoot 1/2 moa all day long. Have never seen barrel since like that one and all I own are barrel burning guns. With bullets now it would be fun to have again.
