.22 CHeetah. I came across a firend the other day that had a rifle made up in .22 CHeetah fro pronghorns and Muleys.
I know that there's the MKI and MKII, the former has a 40 degree shoulder and the latter has a 28 Degree shoulder. I know that the .243 Winchester brass is the preferred brass for making the .22 CHeetah. That's just about the end of my knowledge.

The short barrel life expectancy and marginal ballistics would lead me to look for something more practical, the .243, if for deer.

DOesn't the Cheetah use small rifle primers, so it is basically a 22-308 BR. In the most technical sense, 22-243 is not 22 Cheetah.
Stupid fast, and of course nasty on pipes as are all super fast, terribly inefficient, and ridiculously fun chamberings. But if was a hunting gun, and assuming you could work up a load in say...oh, I don't know...say... 300 shots ;), you would still have 500+ to smoke things with. Prolly need a new pipe in 30 years.

I have had one of each. 9 times out of ten when a big 224 is thought to be burned out it is copper or, of late, hard powder fouling. Removed with Black Powder Gel and other compounds. Derby, you had the stuff in your post right on. It is a fun and flat shootin cartridge and I will build another soon or a 22/6mmAI. Speed kills.

Much better said. Right on RE primers etc but I got tired of forming down 308BR brass and neck turning them and just went with 243 brass necked down then used, large primers and all. If anyone here is taking 300 rounds to work up a load then they are probably starting out with a dog of a barrel at the outset. Especially on a deer and antelope rifle the barrel life would be plenty long and, like you said a REALLY fun cartridge to play with. Everyone really ought tohave one.

The goal of all true rifle looneys should be to burn out as many barrels as possible in ones lifetime.
The CHeetah sounds like a bunch of fun to me.
The Chosin Few November to December 1950, Korea. I'm not one of the Chosin Few but no more remarkable group of Americans ever existed.

Buy the reamer , order two barrels and shoot the hell out of it.
22-6mm AI sounds like fun, after I get bored with my latest project. I'm going with a 338 Ultra Mag necked down to 6.5 with a 40 degree shoulder, that should work wonders on a Benchmark barrel. I'll find out.

Another name for that 22/6mmAI is the 224TTH or Texas Trophy Hunter. A nearby gunsmith uses one with a fast twist Lilja 3 groove barrel to win the regional 1,000 yard benchrest matches.
Luvin the sound of that 6.5/338RUM! Do report on it when you get it all up.

I've a couple Mach One's and like the LR primer route and form with virgin 243 after turning. It's a pain in the ass,compared to say the 22-250AI which I much prefer.
An 8" twist 22-250AI is where it's at and if wanting more,the 243AI is the answer due to better BC's. The 6mm/6mmAI in any guise,is a heavy concession in s/a due to case length.
I shoot them all.

I'm hijacking....but only for a moment.... I have a ABS wrapped BenchMark that will be here in a month or so that I will have punched into 6.5 WSM. This will be #2 in that chambering for me. I built the first one on a LA and I am going to try this one on a short. I know, I know, don't say it. I am building a hunting rifle. Anyway, 6.5 RUM would probably let you get 140's up to almost 3500, 3400 should be no problem given enough tube. The 6.5 WSM on a LA will get you to 3200ish with a 27" barrel. That would be a LR phenom....can you imagine Berger 140s at 3400+? Buy the reamer , order two barrels and shoot the hell out of it.

I thought TTH was 22-6mm without the improved part. I might be mistaken...it happens quite often . Another name for that 22/6mmAI is the 224TTH or Texas Trophy Hunter. A nearby gunsmith uses one with a fast twist Lilja 3 groove barrel to win the regional 1,000 yard benchrest matches.

You could be right, I have not built one. IF it is the un AI'ed 6mm case then I will have to think up another name for the AI'ed version because I HATE trimming cases and will do the AI in a heartbeat.

Fast twist big capacity CF 224s are a blast. I am still pimping 22x47s but am thinking about going a little crazier one of these days. If the bullet companies ever cooperate and build a 90-100 gr bullet that is robust enough for the rigors and has a off da charts BC, I am gonna do something crazy.

So, out of a 700 BDL, the MKII with the 28% shoulder better for feeding out of a magazine?

dd I alway ran my as a single shot. The 40 degree shoulder thing can be bested in the feeding department by the 28.But a good smith can do wonderful things. Once you blow the 40 degree shoulder you can throw the trimmer away...you'll never need it.Cheetah case actually gets .003 or so, shorter on fire forming.And never grows after that. The 243 WCF case is a good starting point. If you read my other posts from the other thread.Theres some very good info there. dave

Thanks Dave. Just read your other thread.
I'm just at the curious stage at this time. Don't know what I'm going to with the rifle. It's been suggested to turn the rifle into a 6MM-250 but who knows.
