Any reason why a 223 or 22 mag could be rechambered into a 222 mag AI or 222 JDJ. How much different is there between the two?

Not sure off the top of my head what the nominal bullet diameter for .22 Mag is. If it's .223", then I'd say "no". If it's .224", then sure. As for .223 Remington, nominal bullet diameter there is .224", so no reason it couldn't be rechambered to a longer case like the .222 Mag or .226 JDJ.

If you have a reamer you CAN make any cartridge Based off the 22 in you Barrel
If you look over and the H&R, NEF guys on this page they seem to do a lot of cal changes to their Barrels

You won't be able to make a JDJ yourself, that is a trademarked cartridge. But Tommy is right, there are lots of options.

No such thing as a 222JDJ... the 226JDJ is based on the 225 Win case, not the 222 Rem case.

Like Keith said, "JDJ" is proprietary and can't be copied with that moniker on it.

I was thinking about sending a barrel into SSK, they will do a 222 JDJ mag rechamber for 75.00 + plus another 75.00 for a custom set for reloading dies. Was just wondering how much different there is bewteen this and a 222 magAI. I would't think there would be very much.

Graybeard · « **Reply #6 on:** October 07, 2009, 06:10:42 PM »

You keep posting 222JDJ but as Ladobe pointed out so far as I know no such round exists. Just what the heck is the round you are wanting SSK to chamber your barrel to?

You are still confusing terms pard. "JDJ" is a J.D. Jones thing and originally developed for TC's... "AI" is a P.O. Ackley thing developed for mostly bolt rifles - two completely different proprietary classifications from two different wildcat developers. Anybody can chamber the AI's, but not the JDJ's without JD's permission. Being rechambered by JD does not make it a JDJ just because he rechambered it.

To be called a 222 "improved" anything, it would be based on the 222 Rem or 222 Rem Mag cases, which are both rimless cases. Even if JD does rechamber your barrel to a 222 "improved" something, it would not be called a 222JDJ something. It could be called a 222 I/AI or 222 MAG I/AI or similar though.

The .224 caliber "JDJ" improved is based on the 225 Win case, which is a rimmed case. It is stronger than either of the 222 Rem cases and has the rim most thought worked better in the break action firearms back when they were developed. IOW, most wildcat/improved cases developed specifically for the TC's were made from rimmed cases (not rimless). Best known for developing them in the old days are JD Jones and Don Bower (the 22 Super Bower, Don's .224 improved, was based on the 307 or 356 Win cases).

If I understand the OP's intent, he's talking about .226 JDJ vs. .222 Remington Magnum AI. I don't know which one has the advantage, but I'd bet the .226 JDJ due to raw case capacity. By how much? No idea.

skb2706 · « **Reply #9 on:** October 08, 2009, 08:55:44 AM »

Throw this in the ring. You can have a 22-204 AI made up that will have the capacity of any one mentioned so far.

J.D. Jones owns and operates SSK industries, makers of gun barrels. I sent them an email inquiring about my interest in a 222 rem mag AI. They replied and sent me a Word document containing information (Powder loads, OAL, speed, fire forming ete, ete) about THEIR SSK 222 JDJ MAGNUM considering that no one even knows that the round exist I guess my question is moot. For anyone who is interested, I will gladly email the 222 JDJ document too you.

I would indeed be interested in seeing that document. My email address should be in my profile.

Not true. The name is copyrighted, but anyone can make a cartridge with the exact same dimensions. The end-result just can't be called a "JDJ."

For instance, if you want a 6.5 JDJ but want it done by another maker, you simply have them chamber a 6.5x.225 AI because that is all the JDJ is anyway.

Likewise with the .375 JDJ. From any other maker, it is the .375x.444.

Thank you for clarifying the point I thought I had made. You are right: you can copy the round if you want but it will not be a JDJ.

Graybeard · « **Reply #14 on:** October 10, 2009, 10:56:14 AM »

Not ALL .375x444 rounds are the same. While it's not impossible to precisely mimic the case dimensions not everyone who "copies" the various JDJ offerings from SSK do so precisely and none of them offer loading data or at least few do and if they are not truly identical trying to use SSK's data could be unsafe.

I do not pretend to follow closely what rounds JD offers these days since I've given up on the TCs personally I was not aware that he is offering a round that he is calling the .222 JDJ but am well aware of his .226 JDJ. Where does one go about seeing information on this round? Is it listed on their site? I do not recall it being listed on the last price list I got from JD tho admit that was a good while ago. He and I used to talk on a kinda "semi regular" basis but we've not talked now for something over a year perhaps even two I just don't recall. I doubt I'll remember to do so but I will try to remember to ask him about this round when he next calls me or I him.

What is the difference in a JDJ 300 Whisper and a 300-221? At one time i called the old Virgin Valley and ask them to make me a 300 Whisper barrel. They said can't make a whisper but can do the 300-221. Than was told it was the same darn thing. Believe me. That was the best shooting barrel i ever owned.

Just to clarify, I have NO intention of sealing anyone proprietary copyrights by reaming up my own barrel. As I said in a earlier post, I’m looking at sending a barrel to SSK (aka JDJ) and have them do the work. After which it will be a JDJ. I’m not saying anyone is implying that, I'm just clarifying.

Hey Sir

Wasn't aware this round existed but then JD doesn't keep me posted on what hes working on for the future. From experience with this company there is much they offer not listed on his web site.

Please send the info to my email address tcdave@suddenlink.net The way my two JDJ's and one JDJ clone shoot I would very much be interested in the 222JDJ.

THANK YOU,
Dave

I ran a search threw google and found this, yes there is a 222JDJ Mag.

http://findarticles.com/p/articles/mi_m0BTT/is_4_33/ai_n31877375/pg_2/

Looks to be as mentioned above no more than a 204 necked up blown out AI version thats already been done with the JDJ name.

Keith L · « **Reply #19 on:** October 11, 2009, 04:59:49 AM »

I like the idea of a rimmed case. I have a spare 10 inch 222 barrel that may have to take a trip and come back a .226 JDJ.

Thanks for the data Hoosierdome. I am seriously toying with the prospect of converting my .223 Bbl.
