Jack Roberts..??? faster 22 caliber...

OK ...

I have a 1 in 9 twist barrel on a Savage 223, that is at my disposal. I will be using the bolt and action from a 243 and the barrel and stock from the 223, to make one rifle and then later I will be building another one (17 Remington) from the left-over parts as money becomes available.

I want to build a faster shooting 22 caliber that I can use for multiple forms of hunting... A 22-250 doesn't quite get it as I need a little heavier bullet (60 - 70 grains)at around 3900 fps on the mild side /ubbthreads/images/graemlins/wink.gif , or faster if I so choose :eek: ..

I want it to be reliable in feeding so I am hesitant about the AI type rounds.

One round that I have looked at is a 22-243 but I don't know where to start with this wildcat?????

Another is a 220 Swift but that would require a rework of the box magazine..

So let's hear it... What would you recomend.......James L.
 
I had pretty good luck with the 22-243 middlestead.I think probably what you are looking for would be one of the Dasher rounds.Dont know how well they feed.
 
A friend of mine is a gunsmith in Arkansas. He builds a .22/6 MM and uses the data from a .220 Swift for his loads.

Don't know what he loads but I'd guess that with a 40 grain bullet, and maybe a 50 grain, you'd be very close to going 4000 fps.
 
My copy of Cartridges of the World, says, concerning the 22-243 Middlestead, 45.0 gr, IMR 4350, under a 65 gr SP, for 3710 fps . 45.0 gr IMR 4831 under a 70 gr SP, for 3420 fps. Good luck.

Tusero...Thanks..

I can get 4000 fps out of a 22-250 with a 40 grain bullet with no pressure signs. Only problem is , it is to light of a bullet for what I will be doing with it...

22/6mm should be pushing a 60 grain partition at around 4100 fps and above according to a recent gun magazine article I read.. That round is also called the 22 TTH (Texas Trophy Hunter). That is if it is the necked down 6mm mauser that you are refering to..

In the same magazine they were pushing bullets fast enough that they came apart :eek: . 60 grain Nosler Partitions were the only ones that held together..

Sometimes I get a need for speed and it needs to be scratched real bad. /ubbthreads/images/graemlins/wink.gif ....

The quest continues. /ubbthreads/images/graemlins/laugh.gif ..........James L.
 
Hi, all I think you would like a 22-250 IMP. with a 1-8 twist bbl. And shoot 80 grs. Mine does real good with 40 - 80 grs. Thanks Clint. /ubbthreads/images/graemlins/cool.gif
 
You are asking too much. A 60-70 grain bullet at 3900 with a mild load is just about impossible and most certainly impractical. You could expect a barrel life of a couple hundred rounds at the very best.

A 22TTH load pushing a 60gr bullet at 4100 is an extremely hot load. First of all, I would have to see it to believe it. If true, it has to be in the 70-75,000 psi range, not a neighborhood you want to be near.

You don't need all that speed. The VLD bullets retain velocity so well there is really no need to have real high muzzle velocity. The 80gr VLDs do very well at 1000 yards when launched at less that 3000fps from a 223.

If you just have to try, I think a 22/284 would be a possible way to do it. Decide on the longest bullet you will shoot and use the slowest twist that will stabilize that bullet. Using the slowest twist will give a few more rounds barrel life before blow-ups start. It is normal for a project like this to wear out a barrel before a good load is developed. Keep spares on hand.

Jack... I made a reference to the 22TTH pushing that bullet that fast.. I was wrong .. It was the 22-284 the article was about /ubbthreads/images/graemlins/blush.gif ... That's what I get for trying to remember stuff /ubbthreads/images/graemlins/wink.gif ..

I am not looking for a barrel burner with short life.. looking like I might have to settle for a few less fps and that 3900 was just a shot in the dark...

Thanks for the input.......... James L.
 
James, I would have to agree with Jack in what you are looking for. No way a .22 TTH will run that vel. Excellent barrel life will be a little hard to come by in those wildcats. As for the .22 TTH, it is just 6mm Rem brass necked down to .22 caliber and only has slight increase of powder capacity over the 22-243. A member of the Cheetah family of calibers might get you what you are looking for but I can tell you for a fact, it IS a barrel burner. I would just shoot a .220 Swift.
 
i own and shoot both the 22-6mm aka 224 TTH and the 22-243. both are 1-8 twist barrels and it is true the 6mm case has a bit more powder cap. but as a rule the 243 case will provide higher velocities. i mainly shoot the 80 gr sierra's for everyting. {shot a hog last spring and got a broadside complete pass through} small hog. exsperimented with lighter bullets. but best accuracy and overall performance comes from the 69 gr sierra's and the 80 grainer's being the true winners. an 80 grn. vld at 3400fps provides everthing i need here in NW oklahoma on coyotes deer hogs praire dogs etc.... most will not believe how much they out perform the 22-250s and swifts with lighter bullets until they are shown or see it for themselves.
 
I've got an 8 twist .22-250AI that I can run 80's at 3350 fps in. That's not a hot load at all, primer pockets have not started to loosen on any of my brass yet after 6 and 7 go-rounds. It's a 29" barrel though, so I'm getting a couple hundred fps for free over a 24".

I was thinking seriously about building a .22-284, but I don't want to go with a really long barrel for how I'll use it. So I think that the capacity is just too much for my application. Pretty much decided that if I go with a .22 bore for this project, I'll do a vanilla .22-243.

By the way, I do have a buddy with a .22-284, and he is getting over 4000 fps with the Berger 64 gr. bullet. He's got a 30" barrel too though.

DAA You refer to a "vanilla" 22-243.. I take this to mean a no thrills deal?????

Tell me a little more about the velocities, twist etc, that you are getting from this round please..

Wallen...How long have you had these two guns? Tell me more.

My barrel is a 1-9 twist and in it's current caliber is a danged good shooter, but I haven't tried to handload for it as the throat is so long I can't get close enough to the lands to get the results that I want from it. Besides, factory ammo is shooting extremely good. I am just looking to up my bullet weight and maintain my velocity.

220 swift at this time is out of the question due to having to change the box magazine ,so the 22-243 is looking better and better....... James L.
 
My 22-250AI is showing quite a bit of alligator hide in the borescope at less than 300 rounds. If it makes it to 600 rounds before blowups start I will be surprised. I expect I will see blowups at about 500 rounds. This is only a 9" twist cut rifled barrel and definitely prefers the 77gr Sierras. Also this is all slow fire, don't even think about rapid fire with overbore fast twist calibers.

With the bigger chambers and higher velocities, an 8" twist is not normally needed. Always use the slowest twist that will stabilize the longest bullet length you are using. A faster than needed twist will only make blowups come sooner. A 223 needs an 8" twist to stabilize an 80gr VLD. The bigger chambers with the higher velocities can use a bit less twist, which gives you a bit more barrel life.

This is a fun neighborhood to play in. Nothing like beating the 300 magnum shooters in a 1000 yard match with a 224. You just need to understand the costs and tradeoffs.

Jack
 
jack, have you tried the qt on coyotes with the 75 gr a max yet?
if you saw the sierra survey on their website you know we asked for a 69 gr blitzking, it was the #1 choice followed by a 17 caliber 25gr blitzking.
 
James, by "vanilla" I mean not the AI version. Just a straight neck down, keeping original taper and shoulder - I would want this to be a repeater.

Also, what I've got in mind is quite a bit different than what you guys are talking about. I'd be doing a slow twist, like a 15, to shoot either 55 gr. plastic tips or the Berger 64 gr. I'd expect well over 4000 fps for the 55's.

My 8 twist is having blowups with full house loads at 700 rounds. If I back them off to around 3200 fps I can get off about 15 shots before it absolutely has to be cleaned and let cool. But it's pretty well done, at 700 rounds. Having it cut off and rechambered as a .22BR. Ought to be able to get another 500 or maybe more rounds out of it at the reduced velocities I'll get from the BR case.

i have owned the 224 tth for five years now. it has always shot well and through the first barrel i got 2300 rnds out of it before the troat went south. this was my first fast twist 22 so i did quite a bit of exsperimenting and i also used as a target and tactical rifle so on ocasion it was severly abused. the 22-243 i built last year and it has shot great from the start with a few 5/8 in groups at 300yrds. i cannot always do this but the rifle has done it in the past.
i know of at least 35 of these {22-243}'s in our country and all that have been shot out has been around 2000 plus rounds. we use a standard 243 case necked down to 22 cal and throated for the 80's 254 necks. i have not heard of one yet that wouldn't shoot considering that the person shooting is remoltly competent at tuning a rifle.
past 300 yards balistically they blow away the fast small bullet 22's
this round bullet combo hits harder than a 25-06 recoils less or equal to the swift shoots as accurate or more to 300yrds and they emberass them past 400yrds.
i dont puss mine that hard at 3400fps i can get more but the gun shoot great there brass life is great bullets are cheap and these guns will kill anything in NW OK with authority.
im not a gun builder or a salesman just my exsperiences with this praticular round,bullet combo. i shoot F-class and hunt with these rifles...
 
While I am not looking for a bench gun or at benchrest shooting, the ballistics and accuaracy sure do carry over into hunting...

Thanks for the information guys. Looks like I am about to enter the wide world of wildcats.

By the way. Where would be the place to get a reasonably good set of reloading dies for a cheaper than dirt price?????? Does redding carry them? .... James L.
 
redding is were i get mine , but i know butch at sportsmans supply has used sets price unknown 580 256 3325 and he will shipp them to you dont forget to haggle w/him.
