    Article about the 22 CHeetah

    I am looking for anyone that would have an article that Jim Carmichel put out that gave specific details on the development, case preparation, and loads for the 22 CHeetah Mk I & II.

    The gunsmith that turned me on to this round has since retired and I can't find this article.

    I would really appreciate it if anyone had one, would send me a copy of it.

    Thanks

    Jim

    22 Cheetah

    Don't have a reference to the Carmicheal article, however, my Hodgdon Manual #26 has a short write up and load data. Since the .308 Remington BR cases with small primer pockets used to form the Cheetah are no longer generally available its probably a moot point anyway. If you want a larger .224 caliber with small primer pocket cases, you might consider the .22X47 Lapua. As it happens I'm having a Kreiger 8 twist barrel chambered for the .22X47 Lapua that should be finished in a couple of weeks. I hope to approach .22/250 AI velocities with a bit less powder. More later when I have a chance to do some testing. Vic

    I read that article

    back when I was in High school. Mid to late eighties. I don't think I can find it right away. But I will look.

    Oh, just in case I would like to know if you mean the Outdoor life article?

    Gees it would be nice if Carmichel would expound on this cartidge.

    M.D.

    I am not sure if it was in the Outdoor Life or not, it's been too long. The article Faster than the Swift appeared in Outdoor Life.

    Thanks

    I read Jim's article and rechambered a 22/250 to the cheetah.
    It did everything Jim said it would do.
    I used remington basic brass(308 with small rifle primer)
    42 grains of imr-4064 gave 4260 fps in my gun but the load was hot,i reduced it by 2 grains and was getting about 4050 fps.
    It was a thunder and was death on crows at 400 yds.
    If you use the .243 brass,it will be thicker and a large rifle primer will drive the pressures up a bit,a 22/250 ackley will do anything the cheetah will do.
    Have fun,be prepared to replace barrel at 500-700 rounds.
    The accuracy was there,i got some groups at .250 but the average group was .4

    I you can't find the Remington small primer .308 brass and have to use large primer brass, then use the Wolf primers. They will be as close to the intensity of a small primer as you will find.

    CHeetah

    I found a reprint of the Handloader .22 CHeetah MkII article by Layne Simpson in Wildcat Cartridges Volume II published by Wolf Publishing Company. Simpson discusses in some detail the ignition problems (hangfires and misfires) that seemed to plague this cartridge. Also according to Ken Howell's book Designing and forming Custom Cartridges the CHeetah case dimensions are somewhat similar, but not identical to the .22/243 Middlested. Case capacity is shown to be the same for the CHeetah and Middlested. I have been tempted to try the Middlested as a replacement for my .22/250 AI's (to use Lapua .243 brass) , but now that I've been able to find good brass for the .22/250 AI's I don't see the need.

    There is a pretty good article in THE VARMINT HUNTERS MAGAZINE, within the last year or so.
    The guy had to find the right powder and end up using LG rifle primers .

    Outdoor Life

    This article by Jim Carmichael was published in Outdoor Life sometime between 1983 and 1987.

    It was interesting not only for the cartridge, but also for Jim's use of a ballistics calculation program on a Radio Shack TRS-80 computer...remember those!?

    I have this magazine mixed in with my piles of other shooting magazines, but it would take me a while to find it.

    Check your local library. They often have back issues in original copies or microfilm. Ask the reference librarian to find it in the Readers Guide to Periodical Literature and locate a copy that you might be able to get through interlibrary loan.

    Greg,

    Unfortunately where I live the librarys are very small and a lot of the books are donated. There is a library about 30 miles from where I live that would most likely have this article.

    I want to thank everyone that has responded to my original post. You all have been very helpful.

    Thank you

    Jim
