I am wanting to try something new,(to me ),a large case,heavy bullet .22 C.F.,capable of doing no less than 3000 f.p.s. with the heaviest slug available,,WITHOUT having to use a 28 inch+ long bbl.,,,what twist,,all that........thanxx

i us a 22/250impv. with the sierra 80 gr in a 8" twist which works well. swift will do the same. there are some heavier bullets out there up to 105 gr i believe, but i would think that they would really have to spin around

HEY BUTCH!! the .22/250 improved was my first consideration,,just waitin' on input about other rounds

224 TTH is basically a 6MM Rem necked down to 224. Generally has a fast twist so as to launch heavey bullets at high velocities for deer.

22-284, 22-06, 22 TTH, 22-250 Ackley, etc.

220 Howell...large case cap., slow powder = low pressure = longer barrel life..with heavy bullets...

226 Barnes Quick Twist.
Velocity only 2700 sorry
bullet 125gr
Twist...1-5.5 or 1-6 if I remember correctly.
Parent case???????

You'll never recover a bullet from anything shy of an ele. Sectional density beats everything else available-all calibers.

Squatch

I got a 22-284. 80gr JLK VLDs at nearly 3600fps.
BC is about .600, look at Sierra's copy.

There is the 308/22 (.22 CHeeta Mk. I and Mk. II).

Heard of the 22 eargasplittingloudengeboomsen? It's a 50 Browning necked down to 224! It was some experimental thing some arsenal was doing. That was the project name for it. Apparently they actually got it to work! It was quite noisy.

FWIW if you build your 22 on a single shot a 28 inch tube can be as handy as a 26 or shorter barrel on a boltgun.

What's this Cheeta thing folks keep talkin' about?
The 220 Swift and the 22-250 are all I know about in the high velocity 22CF domain...

Don't forget the 5.6x57 RWS or 22x57 Rimmed.

Isn't the CHeetah a 22-08 with a small primer pocket? If so, are there any issues with reliable ignition, especially when used in cold weather?

How's the barrel life, Rich?

Use a Savage action and a full bull barrel. That way you can just keep cutting threads in it and cutting the shank off to get a fresh throat every 100 rounds.

I have been playing with a 22-250AI for a while,shooting 80 gr. berger bullets and they are tight even way ouy there.Good Luck

THANXX GUYS!!!Hey 303!,I forgot about the 5.6x57,,probly the 1rst big case .22 c.f.

no need to go exotic when the 250, 22.250 AI and the 220 Swift will do just that...

ya wanna go exotic without the short throat life...22.243...
