View Full Version : .243, .257, & .264 from 22lr mag

Need some help and ideas. I found a bit of info on making larger caliber bullets from the 22lr mag. I have seen .243 (bullshop I think) and a quick search showed somone made a .257 from the 22 lr but I have neither caliber to shoot. I do have a .264 and would like to make some bullets for it. I know some one told me once it could be done from the 22lr mag case. Anyone have some knowledge about a .264 jacketed bullet from the 22lr mag?

How do we take the .224ish dia and bump it up that much? During the core seating stage? I would assume you would derim the case first? Anyone see any potential difficulties?

Thanks

I think you will find that the jackets will split. 25 cal is pushing the limit for RF jackets.
One mans opinion.

22 and 243 are all Ive heard of using 22lr brass

22 mag brass is larger in diameter than 22 lr

Brian,

I've not made anything bigger than .243 out of 22 mag cases. I always thought they would go up to .257, but never tried. I would think 1/4 inch copper tubing would bump up to .264 without too much trouble.

Wouldn't it be nice if 25 and 32 rimfire were still popular and cheap.

I'm really going to have to figure out how to make jackets from copper tubing I guess. I'm still pretty sure someone out there told me .264 was possible or has been done. I'm sure it could be as there is not much I have found that can not be done but looks like it might be a bit of a streach.

Anybody making .264 bullets?

22mag dimintions

Neck diameter .240 in (6.1 mm)
Base diameter .241 in (6.1 mm)
Rim diameter .291 in (7.4 mm)
Rim thickness .046 in (1.2 mm)
Case length 1.052 in (26.7 mm)


22lr dimintions

Neck diameter .225 in (5.7 mm)
Base diameter .225 in (5.7 mm)
Rim diameter .275 in (7.0 mm)
Rim thickness .040 in (1.0 mm)
Case length .590 in (15.0 mm)


I guess I'll have to cut a few cases to get a look at the wall thickness. The 17 hmr is just the 22 mag cases necked down isn't it?

Boy I have never even heard of those 2 rimfires there EH.

There was also a 41 rimfire.

Brian:

If you want to make .264's, either use tubing or draw down FN cases.

A 264 bullet is a real bag of snakes - or can be depending on what you load it in. If you are shooting a Win mag, 6.5-06 or 6.5-300 WWH, the rimfire jacket will not make it very far past the muzzle...

You should have a 22WMR drawn down to .220 for making heavy .224's in that collection. The wall thickness is just not enough to make .257's or anything bigger.

What cartridges do you plan to shoot the .257 & .264 bullets in?

Have a 6.5x55 m94 Sweed. 140 grain @ 2500 fps. Was just thinking about ideas. Drawing down the 5.7 would be interesting. Think I will have to give the copper tubing idea a try some day.

Brian,

Richard Corbin talks about using the 22 WMR and the 22 WRF for making .243 and .257 bullets. I think he removed that article from the website and replaced it with a cartridge bullet making one, but he says if you want to read it just ask me him for it. It doesn't go into how but I am guessing that you draw the case to remove the rim and you have a .243 jacket. To make a .257 you would either use a special core seating punch with a rounded tip to open the jacket as you seat the core, or you could flare the jacket mouth and seat a core that just sticks out of the case once seated. This is the same method used to make .243 bullets from a 22 lr case. I have made .243 bullets from 22 lr cases. No mention of .264 bullets on the 22 WMR case though.

Here is the 25 cal bullet I made from 22 lr the mag would allow a longer heavier bullet and presumably less exposed lead if desired. didn't have any 22 mag so didn't try it.

If a cast lead boolit with paper patch can be driven to 3000fps, then why not a 22LR brass jacketd bullet? Cast a harder core directly into the 'jacket'?

303,

Apparently the rimfire jackets are just too thin for the forces involved. When you add the engraving of the rifling to the jacket along with high velocity and high rotational forces they don't survive too well. Much like shooting light 22 Hornet bullets all out in a 220 Swift, you get a blue smoke trail that seldom reaches the target.

Brian,

I read the cartridge bullet article from Richard Corbin again. He says you can use the 22 Hornet case to make .264 bullets. You have to remove the rim, by shearing it off or turning it off. Then size it.

Thanks I'll look into that. Can't you also make the 22 hornet brass from a 357 mag case. I'll have to look into it but I think it was the latest issue of handloader that did an artical on this.

Thanks

Never mind it was the 22 Rem Jet that can be made from a 357 mag case. A pretty neat process.

Not sure how avialable the 22 hornet brass is. I think I need to find a good sorce for some .25 copper tubbing.

Unless you had a great surplus of hornet brass it would be cheaper and less trouble to just buy commercial jackets.

I have certainly considered just that very thing. I do recall your awesome work with the 6mms and the 22 brass. Stay warm up there.

Even with a harder alloy core? Well OK, I can see why a paper patched boolit would still shoot since the 'jacket', ie the patch, is intended to disintegrate at the muzzle while a thin jacket migh be 'damaged' and fail in flight. Still, out of curiosity I might just give it a try and see what happens - I just won't be expecting too much!

I know a guy that makes a 117gr 264 bullet from 22 Mag cases. I do not know if he would appreciate me posting his e-mail address here, but if you are interested, I can try to get you guys talking. He loves swaging so I bet he will share his secrets.
e-mail me and we'll get this started.

I made a derimming die for 22 mag cases to see if it could be done and it works fine to take the rim off but is a couple thousandths too large for .243. I am going to have to order a reamer to get a smooth interior at the right size.

Have made 270Win 130grain is the max for open tip from 22mag
You should be able to make 6.5
Haven't shot any as yet.(As was mentioned it is a matter of whether
or not it reachers the target.)
made some 87 gr 25cal from standard 22rf to see if it could be done nice (sotpoint)
Made some 100grainers 25 cal from standard 22rf cases. (Large
softpoint
The largest open point i could get from the 22rf case was 67 grains in 25cal

Brian, run the 22 Mag through the 243/6mm jacket maker and then run an expander partially into the jacket. Insert your core and seat and then form your tip. This works on 6.5 and it comes out to about 117 grains. David

Good to know it can be done now I'll just have to get or make the dies. Allready have the rifle and lots of 22LR/Mag brass.

Thanks
