.220 Swift Improved ?

Creedmore · Jun 20, 2018

Good afternoon, fellas. Haven't been around in a while.

BUT . . . the RADD has kicked in, and I'm pondering a new toy. I'm going to buy a donor Rem 700 long action from a buddy, and looking for calibers that I "need".

With all the recent hype about the .224 Valkyrie, I thought - why not go old school and do a 220 Swift? And there is a chambering for Improved, so even better.

Help talk me into it our out of it. Not worried about a barrel burner, as I won't shoot it that much. Just these thin skinned TX whitetails and varmints.

What bullet are you planning on using? That would be my first question. Then what barrel twist? Alpha brass makes 22 Creedmore brass that would put you in the same place I would think without fireforming. The 224 Valkyrie 22 Nosler and 22BR all have the same case capacity. With the Swift I don't think a LA is needed. So you definitely have some things to ponder.

Looking at a 1:7 barrel for longer, heavier bullets. 75gr AMAX, or some of the new 90gr+ pills.

I haven't decided if I want to go this route. Just thinking out loud.

I’ve been pretty impressed with the 22 creedmoor so far, I don’t think there would be an improvement goingbto the 220 swift.

I’ve been running 95 gr SMK IN MY 1-7 twist 26” barrel. It’s definitely worth a look

While being intrigued by a 220 AI as you mentioned (I really like odd wildcats)I will have to say the 22 Creed in a 7 or even 6 1/2 twist would probably do all you want and then some. Add to that you can get Alpha Brass in that and it should be a winner. I'd think anything from 60 gr pills up would be perfect with the 90 gr Fusion bullet or the new heavy Nosler AB in .224 for bambi.

I like the discussion. Becoming interested in the .22 Creedmoor. Tell me more. Is there a quickLoad for the 60gr and 90gr+ bullets?

Isn't the 22 Creedmore close to this wildcat. Towards bottom is case spec.

Yes, I'd say very close.
It's also very close to a 22-250 AI

I've been shooting a 22-243 for several years and the 22-243AI before that. The 22-243 is very accurate and easy to load by simply necking down 243 Lapua cases. An 8" twist has worked well for me while shooting 75-80gr bullets.

Best group I ever shot was .625" shot at 600yds using a moly coated 75gr A-Max bullet at 3,670 ft/sec from the AI chamber. I eventually did away with the AI idea because fireforming cases just wasn't worth the extra velocity.

I've shot 22-250AI and what was interest about case I posted was 30 degree shoulders. I'm shooting 22BR and I have looked at 22CM. I liked your data on 22CM.

0.625 inches at 600 yards! That is some fine riflery! That could put a smile on the face of the most jaded gun crank. Well done.

RADD I forgot about that one.

Thanks Doc. While the rifle shot many tiny groups, the .625" group was never repeated. LOL
The rifle was primarily a groundhog rifle but built more like a benchrest gun.

Many kills were made out to just shy of 900yds which was as far as I had shot opportunities on the farms in PA. Now we are hard pressed to find groundhogs in the ares we hunt. Reportedly, coyotes have killed most of them off.

Here it is with a lighter bullet.
And it has a 30 degree shoulder also.

Code:

Cartridge O.A.L. L6: 2.695 inch = 68.46 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.

Once up on a time in a land far far away I had a 220 Swift in a Ruger 77 varmint. I never shot anything over 55 gr in it but Speer 52 gr Match HP supposedly doing 4000 fps according to the load data back then, did not have a chrno, it would explode a crow or ground hog about as far away as you could see one if the wind was not blowing.
Oh, don't count on using the Hornady A-max they stopped making them. They have the ELD-M now which is supposed to be the A-Max with a new non melting tip but from the accuracy results some are having I believer they changed the bullet some. Many report finding great accuracy then when they change lot number it all goes out the window. I have also run into some very inconsistent bullets in the same box of SSTs, like the base to ogive being 4 thousands difference in measurement with some .264 123 SSTs I was trying to get to shoot in my 6.5 Grendel's. No wonder 2 or 3 would go into the same hole then 1 or 2 would fly out an inch or more at 100 yards.
