has anyone rechambered a 223 to 220 swift ? i have been thinking about this one for a while . i also would like the 224 weatherby , i think the pressures are about the same . secondly , could a 22 mag sportster barrel be rechambered to 22 rem jet and then fit to a sb2 frame ? thanks for the help .

Yes it can be done if you had a 1-12" twist in 223. But why not just buy a 22-250.
With the shorter 22 or 24" 223 barell you never get the benefit of the Swift.

I considered doing so with my .223 Ultra, but after it proved to be sub-MOA shooter I decided to leave it as such. I even purchased a reamer for the job(still may get used on another barrel later).

For those who are considering a 223 to 220 Swift rechamber, I'd seriously recommend the 1-in-12" rifling over the 1-in-9". 1:9" stands a good chance in causing way too much spin, thus causing bullet disintegration with thin jacket varmint pills at Swift speeds.

thanks for the replys , fred you are right about the 22-250 . thats pretty much the same performance as the swift . what do you think about the 22 mag barrel ? is it possible to rechamber and fit it to the sb2 frame ?

What would you wanna rechamber it to?? You could start with a 22 Hornet barrel on a SB2 receiver and save the hassle of barrel fitting.

i wanted to rechamber it to 22 rem jet or 218 bee . the hornet is to long to be rechambered to these calibers i believe , and i have two 22 mag barrels now that i do not need .

Shooter 72
Yes a 22Mag barrel can be fitted to the SB2 frame. Yes the Rem Jet and the Bee are both shorter than the Hornet.

I would take that barrel and turn it into a 22 PPC if the barrel is any good and it has a .224 groove diameter and 1-14" twist. That goes for the Bee and the Jet. I think the 22Mag barrel is .222"

?

In this case it would not be suitable to shoot .224 bullets with any kind of accuracy.
If you want to do something with that barrel then have it rebored to 6mm with a 1-12" twist and chamber for the 6x45 or 6x47, either one is super duper with the 55gr BT bullets.

The 6x45 is on 223 case and 6x47 on 222Rem Mag case

I'm having a 218 Bee done from a 22 mag now ,just picked up the brass and bullets today .

Fred

My 22 mag is a .224 , i slugged it awhile back to see if it would work for this project , Quick checked his and its a .224 too

fred ,
thanks for the advice , i think i am going to do the 22 jet now that i know it can be done . i have always wanted a companion to my smith model 53 and a rebore is a little more than i want to spend right now .

stimpylu32 ,
let me know how your bee comes out , i have always liked the small bore pistol cartridges like the bee and the jet , my favorite is the 256 win mag . that would be a good rebore project !

Knight,

Where did you get your .220 swift reamer? Did it cost a lot? I am thinking about redoing one of my .223 to .220 also.

Midwayusa.com . I think it was about $90 or so.

Greg, you have the option to rent one for about half that.

As Tim wisely pointed out, renting one would save a few bucks.

Thanks Tim, I will check them out. So your a wiseguy now? Cool, when were you made?

About 59yrs ago to the best of my recollection, or so I'm told!!

I've rented 2 throaters from 4D, he's very quick to ship and the reamers worked perfectly. Drinks rented a 445Supermag reamer from him, he had to wait in line as it was being used by another renter at the time, but he finally got it and reamed his 44mag. I got the throaters within just a few days of the order date. They come with no instructions as how to use them, so be forewarned.

Tim,

Do you think I can open up a .223 to .220 by hand or do you think it would be better done on a lathe?

Greg

quickdtoo · « **Reply #17 on:** November 13, 2006, 06:47:28 PM »

I wouldn't do it, my .35 Remington rechamber from 357Maxi was not much more than the cost of renting the reamer and was done on a lathe by a pro, but I know there are those here that have done similar hand reaming, so I'll let them answer as to how it came out and how hard it was. I think Marv did his .219 Zipper by hand.

I agree with Tim doing a chamber by hand is not too good. One of the reasons is that in order to get a reamer started in line with the bore, a starting hole should be drilled with a precision ground drill with a diameter a bit less than the shoulder so the reamer pilot gets to the bore all lined up

Of couse the barrel has to be dialed in so the hole is not drilled crooket. I don't quite know how all this can be done free hand. If you have alredy a chamber and want to do an AI job by hand that is a bit different and easy enough to do.

To do a pood job on a throat and lead a minimum speed of 58rpm is recommended, otherwise you get hack marks in your lead when the reamer skips over the lands.

OK, sounds like a job to farm out in this case. Thanks for the info guys.

I agree with Tim and Fred.

I have access to a full machine shop in my uncles garage - its also partially equipped for gun smithing too. ...so that why I personally chose to buy my own reamer. On a chamber lengthening job like 357mag to 357 max, sure a DIY job is fine, even subtle chamber changes can be done by hand. But a Swift chamber is considerably larger then the .223 Rem.
