22-06 or 22-08?

[andym79]

Hi guys is there or has there ever been a 22-06 or 22-08?

As in a 30-06 or 308 necked down to 22 cal.

That would be so fast it would eat barrels quickly. Would take really good bullets to not come apart midair too.

 

[andym79]

I guess it would be like a 220 swift on steroids!

.22 Cheetah is the .308 Bench Rest necked to .224. I think the .308 BR is a little shorter than the .308 Winchester. There is also a .22-243 which is essentially a .22-308

As I understand it, the .22-06 / .223-06 was experimented with post WWII, but it was abandoned because it didn't perform as well as the 7mm Mauser based 5.6x61 / 5.6x61R vom Hofe Super Express.

I think it would be better suited to step up to a 6mm bullet and push it almost as fast. I believe this would be the best of both worlds as in speed and energy retention and super accurate bullets. Plus you can get light bullets and go a lot heavier if need be. Another plus is that the 6mm-06 and 243 win both exist more widly then the CHeeta and even swift. If you want to stay ultra sonic 22.... cant beat the 22-250. Well known and loaded for on a commercial bases and widely available from many factory manufacturers.

It's all been done, but not for long.

You soon reach a point where you can only push so much powder gas through a small hole before barrel life becomes less then the number of rounds it takes to sight it in, and do load development.

With current technology, the 220 Swift & 22-250 are about the fastest with the mostest when things like barrel life are factored in.

You can only burn so much powder before you run out of barrel. Look at the difference in powder capacity between the .22-250 and the .220 Swift. The Swift case will hold quite a bit more powder, but velocity gains are minor. Going to the even larger 06 case would not gain enough velocity to be worth the extra powder and increased throat erosion.

winchester beat you to it by about 70 years. Try .243 Win, the original 6mm-08

This.

Over the last century, every cartridge has been necked up or down to the extremes, from the .338-.223 straight to .30-06 with a .12 caliber bullet.

When a cartridge becomes as severely overbore as the .30-06 necked to .224 caliber, you see very minimal velocity gains for tremendous increases in powder charge, and severe throat erosion happens quickly (like a couple hundred rounds).

.17 Rem, .220 Swift, 7mm RUM, .30-378 Wthby are examples of maximum practical overbore. Rounds like the .338-50 Talbot demonstrate going a bit too far.

Right after WW II, a couple of wildcatters tried a necked-down .50 to .22. They quickly decided that it was a waste of money, time and gunpowder. I vaguely recall something like 5,000 ft/sec MV. There was discussion in those days about the maximum possible velocity with any sort of conventional rifle.

Might go Googling. I can't recall everything I read, from sixty years back.

This ain't exactly what your looking for, but it is a .22 cal bullet in a 30-06 case !!!

224TTH is the closest thing with any sort of "availability" and with its 7x57 parent case fits right in the middle of 308 and 06 based wildcats

So it's a 5.6x61 Vom Hofe SE with the grooves moved down to American .224" diameter vs European .228" diameter? Huntington still sells 5.6x61 Vom Hofe SE dies under special order group G - http://www.huntingtons.com/store/product.php?productid=19469. Unfortunately, .227/.228 bullets are pretty much non-existent with Hornady listing their one .227 bullet - intended for the .22 Savage High Power - as "Temporarily Suspended", and no other maker offering .227" or .228" bullets.

Also of note, and totally obsolete is the experimental .228 Weatherby Magnum, a necked down .275 H&H Magnum. Interesting read on that one at the IAA forum - http://iaaforum.org/forum3/viewtopic.php?f=8&t=9050&start=30.

"...It's all been done, but not for long..." Exactly. Then it gets done again a few years later. And quickly decided that it was a waste of money, time and gunpowder.
