will a 220 swift fit in a 22-250 box??
or is there an action that will work.?
thanks

not sure how to answer this,, but to your first question no, and to your second, yes.
perhaps if you elaborate a tad more on what you are wanting to do.

ive got a remington 700 adl .22-250 and want a 220 swift i was
thinking i could just re-chamber but then i dont know if the rounds will go in my box.
thanks

You mean the magazine box?

The swift will fit in a short action but the conversion you are talking about will require a new barrel. The Swift is a semi rimmed cartridge and at the case diameter is not large enough for the swift.
The case of a 22-250 is .473 where the case body taper starts and the swift is .445 or .028 inches smaller than the 22-250.

If you are a reloader you can get very near 220 Swift performance from a 22-250AI which is an easy conversion and cases will last longer. Or you can improve on it with another wildcat the 22-243.

FWIW I have a 220 a swift and I enjoy it. However, a good friend of mine had a 22-250 and my rifle did not show any advantage in the paririe dog towns we visited. Being a semi-rimmed round, you must insure the rim of the top round is in front of the rim on the round below it.

I would go 250 AI for the best of both world's.

wow! a lot to think about

keep the 22-250 and add a .257 weatherby magnum to your collection

can i do it with a .222-223.??

I hunt yotes with a .222

but if you want to build a gun....well howdy. I also have a .222r rem 40x barrel and stock. No action though. fix ya right up with it

223wssm beats them both

It works my 22-250 is now a 220swift

Will go 22/250 AI next time not a fan of rimmed cartridge and having to be careful loading so it will feed. Pain in the arse.

Comercial success no, but I do not see any load data for 22-250 or 220Swift that hits 4500fps with a 40gr bullet like you can wiht the 22-243, 224TTH and 223WSSM. The WSSM is less than 1grain case capacity from the 224TTH and gains slmost an inch of effective barrel with that short case

Have it rechambered to a 22-250AI, the swift is a pain with the rimmed case. You can get the same perfomance out of it and better case life. Almost eliminates case stretching.

Never ran 40gr in my swift and doubt 4500 is happening with it but over 4000ft with the 50's is fast enough but the rimmed cartridge is pain in the arse!

Yup, have a few boltactions that take full rimmed cartridges and hear the Semi rimmed Swift is certianly a pain.

One custom rifle in 44Mag that is control round feed actually works quite well even feeds 44spcl, but you can tell the rifle maker took quite a bit of time making that work.

I do not really care about pushing those light bullets so fast, been there done that with the 17 Remington and 20gr bullets at 4300+ not at max loads either. Copper fouling at those speeds is pretty bad.


The OP was wondering if he could just rechamber the 22-250 to teh swift, answer no. But a very good alternative would be to rechamber said barrel to 22-250AI or 22-243 either would work for a reloader

Yank the barrel off the 250 and new barrel 220 I did it and wish I had gone 22/250 ai

thanks guys
