Ackley improved or Ackley changed

[rotorhead]

I concur with Wildcat the swift is the ticket why not just ackley improve it while your at it. I built one and love it. I went with the 1:8 twist so I could fire the larger bullets 69 and 80 grains very very accurate I am getting 3580 out of mine with 4350 and the 69's and I have just begun working loads for it. I used to have the standard 220 swift an it was a shooter as well I only gained about 100 with the AI but I mainly did it because I wanted to make the brass last longer without trimming so much. I use Norma as well.

Here's a thought... you could use the old barrel as a "bang" barrel if you had thoughts of getting an additional custom barrel... get both chambered at the same time, use the old one to fire form brass for the new one... otherwise I'd just leave it as is and get another barrel. My buddy has shot a swift for over 30 years and it's great on groundhogs. I shoot a 22-250 standard and a fast twist... also use a 243ackley improved for the long chucks... man does that rig hit hard! Good luck. Sam

Flybuster,
I have a reamer if you want to give the 22x47 Lapua a try. I love mine. It basically mirrors the 220 swift in performance but with great brass and a small primer pocket. I went with an 8 twist and cannot get the 90s to stabilize but the 80 SMKs shoot great. I have a deer load using TSXs my wife will be using this year.

I like the Ackley simply because there is less case trimming, I think they look great too. So its definetly a feasable option performance wise, when rechambering that old worn throat. I was considering it myself with my Tikka, my other thought was to chamber it in Lapuas new 6.5x47 necked down to .224, havent heard alot of field reports on that one.

Eddybo, do you have more info on th 22x47? I would be interested in info.. could set one up for the 40-55 grain pills... been thru the 22-250's regular and fast (8 twist) and looking to play with an interesting chambering in 22 for groundhogs.. not interested in a 22BR. Please advise.. thanks, Sam
