For case forming I use imperial sizing wax, if you haven't tried it you should give it a shot- great stuff and easier to clean up. I use it when I convert Lapua 30-06 to 6mm Rem Ackley.
Yes, what Patrick H.said, below, .22-243 Middlestead. The "Cheetah" is a 308 w/small bench rest primer and is a big process with regard to sizing down. My Middlestead has a .248" neck so I have to neck turn. Good stuff here, thanks because I was just about to fire form some brass but didn't want to shoot my bullets up. Granted my fire form loads were very accurate to 200yds for groundhogs so I use to shoot hogs up to 200yds which kills two birds with one stone, but now I want to form without using bullets and this will help. Thanks!
A lot more volume in the 243 case. I'm not sure a 22-250 case would like that much expansion. The 243 case is already getting expanded enough with the Ackly Improvement.
Thank you for the question and the sub : ) The believe the CHeetah was started from a 308. So I would say yes. 30 to 22 might be too big of a step tho. You might want to take it to 243 before the 22 and watch your neck thickness. If your shoving the necks into the shoulders, it's too big of a step.
Most likely yes. Would probably help to either run it through a 243 die first, as mentioned, or purchase the 22 CHeetah forming dies. The CHeetah was originally formed from Rem 308 BR brass that is no longer manufactured. I believe the brass was a bit thinner than military brass, but the big difference is the BR brass has a small rifle primer pocket. The closest thing available today would be the Lapua 308 Palma brass. When I bought my rifle it came with the forming dies (around $400 new) and several hundred pieces of BR brass so that is all I've ever used, however, I'm curious to see if regular Lapua 308 brass or LC LR brass are any better/worse than the BR brass. The forming dies can be found on ebay from time to time for around half the price of new ones.
@earl verity It's nice that dies can be purchased now-a-days. Back when we first got the Cheetah, we had to have dies made for us. The gunsmith used the Cheetah chamber reamer on a set of 22-250 dies if i recall correctly.

That is a wild sounding round . Thanks for showing .
Nice project ! I have the same rifle in 22-250, I bought it (2nd hand) because of its excellent stock

Had a cheetah 10+ yrs ago pretty cool round.
Thank you for the comment :) This CHeetah has been around since last centry : )
I use Lapua 243 brass, the 5 grains of fast pistol powder and cream of wheat with a small waded up paper towel to fire form-no bullet. Works very well
Yes it does : ) I just did 100 lapua for my 243 that way.
So is the 22 Cheetah and the 22-243 Ackley Improved the same thing??? They both have the 40 degree shoulder correct?
pretty much so. Back in the day they used a small primer 308 case but it's all about the same.
So is this is just like a regular 22-250 cartridge. Seems like a lotta extra work when you could just use 22-250 brass, am I missing something here?

The 22 CHeetAH is supposed to have a small primer pocket. What you've really made is 22 Middlestead.
Made on 308 match brass, good luck finding that now a days.
Any chance that you could form this from7.62x51 military brass.

22-250 case lenth of 1.912" what is the cheetahs over all lenth? Same as .243?
Pretty close I use 2.000 on the CHeetah's
You could use a 6mm supper lr Cass to make this round.
So basically a 22-250?
More like a 22-08 The Ackley improvement actually allows it to hold more powder than a 308.
A 22-250 is actually the old 250-3000 (250 Savage) necked down to 22 caliber. However, same BOLT FACE as .308.
Mark 1 or 2
It's the Mark 1 with the 40 degree shoulders.
If dont mind me asking where did you get your dies at I bought a rifle the other day an turns out that's what it is
@@jamesbanister3866 The die set came from MidwayUSA RCBS #56036
