Home Forums Hunting & Shooting Custom Rifles & Wildcats If you were to build a speed demon what would it be.

I shot a 17 Rem for yrs and it was a heck of a Fox rifle. But if I shot a Coyote in the shoulder at 200 to 300 yds they were runners. Just not enough bullet or energy to do the job like a 22-250 or a Swift would do at that range with 50 to 52 gr bullets. Thats why a want a Rifle that has speed and a pretty good bullet.

In that case, build a big 6 shooting 55s for the point and shoot coyotes, along with some 95 or 105 grain Bergers for the long range, take your time coyotes.

I'm switching to monos out of my 22-250AI. I was getting kabooms on impact due to the high velocity, which resulted in a wounded dog hauling ass into the sunset.

What bullets were you using and what velocities? I am contemplating building one of these and would appreciate the info.

You want fast..there ya go.

I haven't read the whole thread, but I built a 22-284 several years ago. I used up to 90grain JLKs that Jimmie Knox was fooling with at the time. They just evaporated. Kept slowing it down and it shot pretty good. I found it was really hard to beat a 22-243.

The 22 CHeetah.



I ended up running 52g Berger bullets at about 4100 FPS.On my first rifle.
My second one was even faster.
Need about 2.75 of up, from a 100 yard zero, to be on, at 400 yards.
I killed piles of chucks from 350 to 600 yards.
Do it right and run light bullets with the 1-16 twist.
Instead of that turd lobben stuff...
If you cant get BR brass.
The I'd look real hard at Lapua Palma brass.
Just dont try to use the small primer stuff in cold weather.
Barrel life is rather "short".

Dave, had a Cheetah when they first came out..a great shooter and super chuck rifle..In those days I shot the Nosler BTBT in 50 grain...

84, I have a 22-250 AI and have shot it for about 18 years..At present it is about 2400 rounds old and a I have had great success with it on everything from prairie dogs to whitetails..I often shot 64 grain WW on deer, but my favorite bullet is the 50 grain Blitzking..I am not sure just how many coyotes but far more than a few..It is my favorite .22 caliber for coyotes after my Swift..I have had no bullet failures..the last time I checked the speed, it was about 4050fps..

For two 6/06 barrels I've used a combo close to that. The 55 NBT at well over 4K has been awesome on called dogs. Miss the big bones and there's lil to none at all exits. We've used the slug to take some lopes and deer as well.

Our main reasons for the 55 NBT was to have a fur friendly load.

WCH-another bullet I've long loved is the 63 Sierra (I call it old ugly). Accurate as they come, fur friendly and very game capable.

Mark, that is another one I have used a great deal, but mostly in my old .22-250...I shot it some in the AI, but somewhere along the line I bought 500 64 grain WW so have been shooting those..But those old 63 grain bullets are one of my favorites also..

I can remember running 50g Sierra SPs up to 4300fps.
That was with the big gun.
I did try it on a few chucks.
It was a blast so to speak....
Mine operated at and I kept at,just under 4100 fps with the 52g Berger.
Both of mine shot real well there.
It messes up the clock in your head when to see an "instant" bullet impact 650 yards away.
The 22-250 AI is a more practical round.
But its not as much fun.

How bad do you want to tear them up? Accurately....
- 4200 with a .223AI and 40's.
- with a 22-250AI....well over 4200 with 50's and 4000 with 55's.
-70's through a 6mmAI doing 4150, quite a bit faster with lighter bullets.
-Or a 257Wby and 100's @ 3850 with a 26" barrel, 4000 with a 30"barrel, a lot faster with lighter bullets.

Over 4200 is awfully d#mn fast, 4000 is cooking along real good.

My speed demon would be a .358 Shooting Times Alaskan (28" bbl)...coyotes and much more.

I just don't believe some of these stated figures, or I have a slow gun -or- I have a slow chrono.

I am at 4266fps with 40's out of my 22-250AI before I started feeling a stiff bolt from a 24" barrel.

I am at 3850 with 40's out of my 223AI with a 22" barrel before I started feeling pressure.

Your numbers are about what I've seen as well (except the 22-250 AI was a Swift). 4225 for a 25" Swift, 3850 for a 22" 223 AI.

Yeah, those figures (of Ackman's) are ridiculous. I get a bit better than 3900 fps out of my 223AI with 40's and a 22" barrel. I am leaning on it about as hard as I care to.
I don't doubt that can be improved on with longer barrels and at the edge loads. But 4200 with 40's out of a 223AI is in no way a balanced description of what to expect from a 223AI and 40's.

Always funny when someone calls bs if they're not getting the same numbers......since they're not doing it, somebody else can't do it. Nothing ridiculous about those numbers. Targets are all filed with chrono tape attached. Pact Pro chrono checked against my friend's Oehler 35.....within 20fps of each other. There's nothing magic, just brass/powder/primer and chamber, anyone can do it. I know others who are. Instead of calling bs, tweek your own stuff and get it working better.

*** I have 4 - 223AI's all 14" twist, chambered with the same tight reamer - .250"nk 0 freebore. The 3 that I've shot.....25" Schneider, 24" Douglas/Virgin Valley, and cheap 24" A&B. The same 40gr load that's 4100fps in the Schneider, is only 3950 in the Douglas and 3900 in the A&B. I'd expect a top-quality match barrel - or one with a properly sized bore - to equal the performance of that Schneider. The 22-250AI is a 28" Hart and another 25" Lothar Walther is just as fast, both 14 twist. The 257Wby is a 12 twist 29" Hart. The 6mmAI is Krieger. All chambers are semi-tight neck with 0 freebore and about .010" longer than the brass. Well spec'd chamber and barrel make a difference.

dave7mm,Those Cheetah's are some rifle..I think mine was the most accurate rifle I ever owned..I have thought of putting another together as I still have dies, etc..right now I am .22 caliber poor, and don't get all the rifles I have shot each summer since the prairie dog shooting here has become a rich man's sport..Still when one of my big .22's goes, I have a new Douglas barrel, I might just make up a Cheetah..!!.I loved shooting crows with that rifle..Had the first 6.5-20 Leupold I ever owned on it..Crows looked huge in that after using nothing more powerful than a 10x..With a good hit, crow parts rained everywhere.....AHHH times passed.

When I get around to it.
Im going to rebarrel my old one.
I'd like to build new.
I have a stock.
But need everything else.

In time ....
