Anyone tried one? Any advantage over a 22-250?

John

Eddybo (RIP) ran one. IIRC, case capacity on par with Swift, but Lapua brass. Of course Lapua now makes 22-250 brass. So the question I'd ask is, why not 22-250 AI running Lapua brass? Fire form and roll. In the end, it's gonna be up to personal taste.

While it's not built at this time, Beanland is going to build me a 22x47. I have several 80 Amax that I want to shoot with it

Thinking I'm gonna just go with 22-250 at this point. 8" twist, of course� Sometimes the easy button is not a bad thing.

And when the easy button is paired with ready-to-rock 22-250 Lapua brass.... that's a really good easy button.

Question: Is Lapua brass that much better than the others?

Curious.

A handloading looney consideration for the 47 Lapua case is the small primer pocket. Evidently you could run higher pressures and get more velocity with the small rifle primers.

But necking down cases, concentricity considerations, etc wouldn't make the 22-47 worth it for me. I would never be able to tell the difference between the two primers anyway.

Yes, Lapua brass is very good. The additional cost depends on your pocketbook tolerance, I guess. If you anneal the Lapua brass after 3-4 firings it will last a long time.

Well I'll not sure about any advantage.
But.
Theres the cool factor.
Alittle Imperial sizing die wax and a 6.5x47 case will turn into a 22x47 with very little effort.
Without going to the extra effort of improving it before you could actually use it like a 22-250 AI.
Its long neck and 30 degree shoulder are considered "ideal" for case life, barrel life, and accuracy.Very little trimming will be needed.
It will run pretty much same same as a standard 22-250 speed wise with less powder.The 22-250 will actually need more powder to equal what the -47 will give..its that peskey case efficiency thing.
The 22-250 is state of the art 1960.
The -47 based case is where its at today.

I'm reading the x47 case holds a little more than the 22-250 case. Not true?

Hondo, I assume you've read this thread by now (the first google hit when you type in 22-47 Lapua).

http://forum.accurateshooter.com/index.php?topic=3765707.0

That gentleman says case capacity is between the 22-250 and 22-250 AI.

The thread also talks about some difficulty getting good 22-47 Lapua sizing dies. Of course custom dies are an option, if you have some time and a little more money than for regular dies.

I read it. I like the idea of the small primer pocket and minimal case trimming. I doubt performance would be any different at similar pressures. But, availability of Lapua 22-250 brass as well as mainstream brands and being able to buy factory should the need arise is kinda weighing in favor of the 22-250 for me right now.

Now if someone who has run both chimes in and says the 22x47 Lapua is MUCH easier to get to shoot well than a 22-250, I might take notice of that. Don't know if that's gonna happen though as the 22-250 has a very good reputation of being inherently accurate�

If you choose 22-250, my vote would be to put the Ackley spurs to it. I can't think of a drawback... as my Ackleys all shoot fire-form loads surprisingly well. I have a couple of 7mm-08 AI's, and for one of them, I had trouble finding an AI load that shot as well as my FF loads... til I found the magic potion.

Don't overlook a fast twist 22BR - throated for heavies...

MAYBE we will see a commercial 6CM and 22CM on the Creedmoor platform. Time will tell.

A 22 Creed sounds like a winner. Although, not sure I really need more out of a 22 than a standard 22-250 delivers.

Base brass only difference for a sure feed repeater, a 22-250 is a good one, the AI would reduce stretch, as a CM or 47. BR case is best a single feed in this cal.

I don't know if this is or could be a issue with the X47 small rifle primer but!

With my first 22-250 AI I had an idea to try the Remington universal benchrest brass with a small primer.

Brass worked well until the first 0- cold day hunting coyotes in Colorado I had a few hang / misfires with IMR 4064 and Remington 7 1/2's.

kevin weaver in CO has reamers for it.

I worked up loads for a friends 22/47. It had a negative muzzle brake. I could see my hits as I shot. It came with Newlon Precision dies. It would put 10 rounds in one ragged - very small - hole with little effort. It was built by Charlie at ScoreHigh gunsmithing.

I'll be building one soon.

6W - good point, it seems as capacity goes up, and caliber down, a SR primer may be an issue in the colder temps. An issue in some areas.

we have been doing a good number of 22 creedmoors, running from 3480-3600 fps with the 75 amax, run those numbers and see what you think
