I have a Savage model 10 I bought specifically on which to build a left handed 220 Swift. I am in the planning stages right now but am considering making it a fast twist, say 1 in 9, to handle some heavier bullets.
My ground squirrel and P dog days are over for the most part. I haven't been in many years and most of my shooting will be sniping coyotes, wolves and paper at potentially longish range. I assume a 55 grain will still do alright in a 1 in 9. How well will that twist handle the 75+ grain bullets? Should I consider a 1 in 8 and how do those two twists handle the light bullets, 40-50 grains?
In all the varmint guns I've had over the years, I've never had a fast twist 22 centerfire. Thought it might be time to give it some consideration with this build. Thanks in advance.

Tried 40 gr Vmax's out of my 1 in 8 22-250ai for the fun of it and they shot fine, along with everything else I tried (except the scirrocos for whatever reason.)

If you already have a bunch of 220 swift brass I'd say run with it but if you don't I'd go 22-250 Ackley. Seems like 220 swift brass is seasonal anymore and is tough to find around here anyways.

I have a ton of 220 Swift brass, and much of it new. I am one of those guys who buys it when I see it so I've amassed a goodly amount.

Any drawbacks? Nope. Do yourself a favor and go 1-8" twist. Light bullets shoot very well with a 1-8.

I can't find any drawback to a 1-8" 22-250 and if I were building a Swift I'd go 8".

My 1/8 twist 220 swift actually shoots 55gr bullets as accurate as 75gr. bullets. My 1/9 twist 22-250 handles 75gr Amax's fine. I am at 3500ft elevation though. I believe the 1/8 twist is the way to go. Brian Litz says marginally stabilised bullets lose some of their B.C. Go 8 twist, no downside.

My latest Swift is a 1 in 9 twist and while I have yet to really wring it out, initial testing shows it to not be very particular about bullets. I may even try some 36gr Varmint Grenade's to see if I can set a new world record for ground squirrel "lift"

I'm getting ready to build a fast twist Swift on a LH 700 Action with a Shilen 1&8 twist #4 SS Select Match Barrel. I have already purchased 200 Norma Cases and 600 Hornady A-Max's and Shilen 1&8 twist barrel for this build. The reason i haven't started is the Reamer i have has a custom.244 neck and i will have to purchased a Redding Bushing die and i will have to turn the necks if i use this reamer and not sure this is the route i want to go. I think I'm just going order a standard 220 Swift reamer with bushing this week from PTG and then chamber and finish this build after Christmas . Will post photos when done. If you want to shoot the light bullets then the 1&9 twist might be just a little better , but the 1&8 will give you a great advantage over the 1&9 if you choose to use the long 75 gr A-Max's and this is the only real advantage in using a fast twist barrel on a 220 Swift or 22-250. I will start loading with IMR 4350 powder .

That settles it. It's going to be a 1 in 8 Swift.
