Hot rod small bore centerfire

[steelslaver]

I got a bug for a small bore centerfire revolver. I have a spare K frame 22mag cylinder and will probably line the barrel. I was thinking of 22 Cooper centerfire magnum, Think the bottle neck cartridges like the 22 jet often.have problems with backing out and cylinder rotation. Am I wrong. Whats best? Might make a 25 caliber from hornet brass.

I don't know it has been tried yet, but how about a .22 TCM chambering? You can at least find the factory ammo for it.

Rimless case would mean moon clips which I could.make but don't want to

Try the Kay Chuk. It's a wildcat from the early60s and there were a few commercial guns made.

The brass is made from Hornet brass, shortened .050", and chamber formed.

None of the problems of the Jet and it's just as much fun to shoot!

You don't have problems with the cases backing out etc. I had a 32-20 once and it was finicky. The K-Chuck looks good if the cases don't back out. Making the brass looks similar to my 30 and 357 Herrets.

Reasons I hesitate on the 22 CCM is brass is difficult to make as you need to turn the base and rim of the Hornet case, dies are listed at $177 and I don't have a clue how much a reamer would cost me.

I've been wanting to do a .22 Kay-Chuk conversion for ages. I even have a spare 17-4 8 3/8" barreled revolver that might get sacrificed. Main hold up is deciding whether to convert the 17 to centerfire or utilize an ugly but excellent shooting Model 19 frame. That or a Post-'94 D&T framed something.

My .22 Jet has not suffered from the cylinder lockup drama. But it's throats are huge! 0.227"+ Bullets of 0.224" diameter fairly well rattle through, so accuracy at distance is generally disappointing. Thus, doing a conversion seems the ideal way to get everything just right. I wouldn't mind if it works out where 0.223" bullets are best- have plenty of those.

Would do another cylinder for the Jet, but it's oddly long and won't work with the usual .22 rimfire cylinders. And no way the rimfire cylinder that came with it is getting modded!

I think that you can use a regular K Hornat reamer if you don't run it all the way in, but you'll have to cut the recesses in a separate operation. Floating pilot sized to the throats. Otherwise you'd need a special reamer done. Thinking I'd rather just rent one!

Sounds like the Kay Chuck is a good option. I have also thought of making a straight walled 25. Make a die and run the brass in to get the bottom of the brass right, maybe have to turn it a little near the base. Use a 25 cal expander to open up the rest up then shorten, load and fire form first loads with light charges. Would have o get a reamer made and make my own dies though. Should be fun with 60 gr bullets. But a 224 based round means dies and reamers available plus a better selection of bullets. What kind of velocities would I be looking at?

I wonder if you could use 9mm moon clips with the 22TCM ?

RCBS has dies for a .25 on a Hornet case.It is called .257 Magnum. There was an article in Handloader #81. Looks real interesting.

The Jet's so-called backing out problem is more a causation of the reloader/gun cleaner than the cartridge design. If one keeps the ammo and the cylinder chambers clean and free of any oil it was my experience to never have a backout problem. All I had to do was to add one small final step in my reloading of the Jet and that was to wipe each and every loaded cartridge with a rag dampened with common household alcohol before placing that cartridge in the ammo box. .............

I have thought about using a mod 66/67 frame, 8 3/8" 617 barrel and cylinder, and have it reamed to the Kay Chuk. With my present Kay Chuk, from the Bennett Gun Works, I only neck size the brass and reload! You can deprime with any 22 cal dies(.222, .223, Jets, Hornet). If you have a reamer made you are half way to a resizing die!

I have a lathe and have thought of making my own dies. But, wouldn't a resizing die need to be slightly smaller than a chambering die? I have 222, 223, 22-250 and 220 swift dies so no problem there. LOL But, could I just get some Hornet dies and run the reamer in those?

I take it there would be no need to crimp such a load even in a revolver because of the low bullet weights? Just a 2 die set like rifle dies?

You have about got me talked into the Kay Chuck. I am bidding on a 22 mag barrel and would rather run 224 bullets than 222. Have made a deal for a model 10, will mill and install adjustable sights and already have a 22 mag cylinder.

[jcelect]

No Hornet dies to make the Kay Chuk dies! The brass has been shortened by .050". The best reloading dies are the ones made form the reamer that chambered the gun. When making the die you don't go in as far as you did on the chamber. Just buy a Hornady .224 short neck sizing die & a Hornady .224 bullet seating die. Your mod 10 frame might not work! Mod 10 cyl is 1.56" and the mod 48 cyl is 1.62".
I have an original sheet of reloading data that Jim Harvey used on the first Kay Chuks. He used .224 35gr Sisk bullets(long gone). I shoot the .224 35gr Hornady bullets(the one in the picture) and have had no problems. However, I have wondered how a 22 mag barrel would work in regards to accuracy? ! ? Email me your snail mail address and I will send you a couple fired brass. You'll need them to have the reamer made!

The window on a model 10 should be the same as all K frames, I can adjust the barrel to fit the cylinder. .06 shorter cylinder shouldn't be a problem except maybe on longer bullets. If I stay below 52 grains the 1 in 15 twist should be OK. That is what Jet barrels run for a twist also. I had a 222 Remington with a 1 in 14 and it did fine with most 55 grain bullets and loved the lighter ones. If I have problems I can drill out the barrel and line it to 1 in 12. I have several thousand 40gr 2224 bullets already from when I had my 222.
