220 swift

[jghoghunter]

There isn't anything that a 220 Swift can do that a 22 Creedmoor can't surpass.

WOW
Santa must have brought you some of that white dust he gives his reindeer to make them fly. Build, since you cant buy a swift to shoot say 85 gr. bergers and leave the needsmore in the dust!!

If you go the custom rifle rout, a 220 Swift can be chambered in a 7.5 twist. My 8"twist 22 Creedmoor shoots those 85.5 gr Bergers just fine.

A 22 Creed is nothing more than a 22-250 improved. I've heard this crap all my life about how improving that cartridge is equal to or slightly better than the Swift. Fast twist barrels and high pressure powder charges do miracles. Blah blah blah. What if you improve the Swift cartridge? Go to a fast twist barrel? Load more powder than is safe in the cartridge? The 22-250 is left in the dust again.

Case capacity = fuel capacity = horsepower.
I've heard all about efficiency. The bottom line is can a small block run with a big block?? Yes. However, if you do the same things to a big block as you do to a small block - the big block wins every time!!
Put an 8 twist on a Swift, put a sharp shoulder on a Swift and it will stomp the Creed ad nauseam.

Long live revived posts!

Back in the early 90's I was going to build a 22/250 AI, told my Pap, got slapped in the back of the head. He said how dumb are you? Why would you take something smaller and make it ALMOST as big as something else you can buy off the shelf. Start with the biggest and make IT bigger. That was my first 220 weatherby rocket. There are a few people on here that don't understand the rules of physics. When you take one cartridge and make it as big as another one then all of a sudden you get velocities that trump the bigger cartridge by say some 2-300 fps and then they tell me it's all within the pressure limits and its safe. I say let me know when your shooting it at my range so I can go home because I don't want to be part of the investigation someday on how that guy lost the side of his head!! Incidentally those people are on my ignore list now and have been for a few years.

Please remember I'm just having fun. But when you start comparing apples to apples the needsmore is "just fine" before the needsmore would "surpass" the swift.

The mighty Swift was introduced in 1935. Now, 90 years later, engineers have figured out how to EQUAL the great 220!!
When comparing cartridges, as it has been noted, we must assume equal twists and loaded to equal pressures. Otherwise, it's not apples to apples.
I'm not saying that I'm not going to try the 22CM, I've got one in the works. Hopefully it will at least equal the performance of the Swifts that I've owned.
Long live the Swift

Howdy !

As regards your comment, above….

The standard .220 Swift has a mild 21* shoulder angle…

When it comes to case modification(s):
IF you were to only sharpen the shoulder angle as mentioned….case capacity would decrease; as the area for powder underneath the shoulder would be decreased.
With the 21* shoulder angle of the slim standard case, this powder space is significant.

Additionally, the use of a longer/ heavier VLD bullet ( implied by the suggested twist ) would pretty much negate any powder space increase from the slightly longer neck a sharper shoulder angle might introduce.

To gain powder capacity along w/ using a sharper shoulder angle, the case’ shoulder diam would also need to be “ blown out “ to a larger diameter.

Not trying to be a wise a_ _ .

The case blow out was inferred within the sharp shoulder concept. I just kept it short.
Even with VLD's, I wouldn't seat below the neck/shoulder junction in any case, not just the Swift. Even in 300 Savage wildcats (Titus and IHMSA line) and in 284 wildcats, I don't seat below the neck/shoulder junction. If I had any 300 WM wildcats the same principle would apply.

Ruger 220 Swift 1 - 14 twist shooting Hornady 52 gr Match HP. Them bullets have killed 100's of Coyotes and Red Fox

I have 22-250 AI and they are not as fast as the Swift

I have a 7 5 twist 22 Creedmoor. I want to build a 22 Creedmoor in a 1 - 14 twist and compare apples to apples. Running the 22 Creedmoor up against the 220 Swift and 22-250 AI. All of them with a 14 twist 26 inch barrels. And Remington 700 actions.
I would love to rechamber my Swift to a AI but it shoots to good to mess with.

Cowboybob -

Howdy ! Thanx for clarifying.

Thinking out-loud….

If you impart “Ackley Improved “ features to the .220 Swift case, you will be
“ wildcatting “. You’d still be faced w/ the long cartridge o.a.l. when shooting VLDs.
Perhaps a non-issue…. if shooting these long cartridges from a single shot action.

For a shooter that has a bunch of .220Swift brass, and also a rifle(s) already set up for the case; wildcatting the stock case ( as mention ) makes sense.

At the same time…. wildcatting a different “ parent “ case could provide the desired case capacity, while enabling control of overall loaded cartridge length. This process could also apply in instances where a shorter loaded cartridge oal is desired for a
magazine-fed application.

.22-47L, .22XC, .22 Creed…. they too are wildcats, each one with a different case capacity. You’d be verifying where the ‘Swift AI lies on the .224” cal wildcat’ capacity “ line “.

I have 3 220 Swifts and at least that many 22-250's and a very healthy supply of brass for both cartridges. My preference is still the Swift. That said, the 223WSSM is still faster. Haven't played with the 22 Creedmoor yet. Bought the 223WSSM to hunt pronghorns with. Haven't made it yet. Bucket list.
