    Here is my predicament:
    I've been thinking about building a fast twist .22 cal wildcat for awhile now. First off, I can't seem to find conclusive date that what I want is even doable. What I want is to push a 75 grain bullet at 3500 fps out of a 26 or better yet a 24 inch barrel.

    I was thinking about either a 22-243 or a 22-6mm Remington off a Rem 700 short action, but with the arrival of the 6.5x47 and 6x47, I got to thinking why not a 22x47 althought as far as I know no one is chambering that or making dies yet.
    Anyway, any thoughts or advise would be much appreciated.
    Thanks,
    Matt

    22x47 works good and the brass is great. I have two, one in an 8 twist and one in a 7.5, and also a 14T barrel that I switch out. I only built them as a way to use up all my old 6-6.5x47 brass that was to used for f-class matches. I do not take the most care when forming the brass, one pass through a .255 bushing in a redding 6.5x47 die and my 6mmx47 cases fit in my 22x47. I took one of them prairie dog hunting this year shooting the 90 berger at nearly 3200 I was able to make a bunch of near misses on dogs at 1400 yards, but never connected before I ran out of ammo. I also took a 22x47 14T that was used for the brunt of my shooting 40gr bullets at 4300 with ppc accuracy worked great. We made several hits at 900+ using the 40 grainers.

    Matt.

    I was also looking for something very fast and was not worrying about barrel life so I chose
    the 223 WSSM and I have not been dissapointed.

    After doing as much research as I could and getting as much information as possible on this
    Web site I decided on a 1in15 twist because some of the learned members said that a fast
    twist would destroy most bullets at the kind of velocities I was looking for. (They were dead
    on).

    To date I have pushed the 64gr to 3915 ft/sec with a SD of 0006. and a 40 gr to 4351ft/sec
    with a SD of 0009 with no signs of bullet problems and group sizes just over 1/2 MOA without
    accuracy development.

    Also I am using a 3 groove Lilja hopefully to improve barrel life "Some" all the votes are not
    in on this decision yet but so far it looks to be the right one.

    Just a thought

    eddybo,
    what kinda speed do you think a 22x47 would get with a 75 grain bullet out of a 24 inch barrel? Velocity should be slightly better than a 22-243 no? Who did you barrel work?
    Thanks,
    Matt

    Never tried any of the mid weight bullets so have really no idea. I would guess that the 22x47 would push them fairly well. Since I get nearly equal performance from the 243 as the 6-47 I would guess that the same would hold true in 22s.

    That 223 WSsM sounds interesting also. I wonder if anyone has tried them in a fast twist for the heavy bullets. I suspect that the limitation would be the bullets themselves. I can push hard enough with the 22x47 to blow 90gr bergers up with my 7.5 twist, but have not lost any of the 80s in my 8 twist.

    I too am a 22 cal fan. I chose the 284 platform. I had a 22-284 built and would not change a thing. I am shooting the 70 grn barnes x bullet at 3818 fps and the 75 grn v-max at 3788 fps with no primer loosening. Its on a 700 short action with a 26 inch shilen select match barrel one in nine twist. Cant say a bad thing about it groups under half inch and boy it hits like the hammer of thor.

    I have read with the WSSM they are having problems with bullets exploding because of the high twist rate. J.E. must have found this out as well. I think it would be cool to have something shoot the big ones fast. I just wonder if you could open up to a 1:10 with the heavier bullets because of the speed being so high to compensate for lack of twist. Anybody ever try this theory?

    Yes.
    That is the reason I chose the 1 in 15 twist (for lighter bullets @ 4400+ ft/sec).

    I use to have a 22/250 with a 1 in 14 twist and it did very well with 52 to 55 gr bullets
    @ 3800+ ft/sec.

    My main goal was to see just how fast I could push a 40gr Ballistic tip and not lose
    accuracy.

    So far I have reached almost 4400 ft/sec with no pressure signs and accuracy has been
    getting better even though I have not tried to improve accuracy at this point.

    Brass is holding up well in the 223 WSSM with 4 firings in them. (I took 40 rounds out of
    the smallest batch of weight sorted cases) and intend to use them up during testing.

    All of the holes in the target are clean so the little 40gr ballistic tips are holding up.

    22/6mm AI easily pushes the 75 gr AMax to 3950. I run mine at 3700 to make the barrel last as long as possible.

    I think I'd go with .22-250 Ackley Improved with 1-9 twist 26" barrel. Keep it simple.

    Rich at Sierra Bullets technical dept. shoots a 22x47. He is a good guy and would be glad to help you. I shoot 80gr smk's at 3230fps with good results.

    I had a .224 hot rod idea last winter then after reading thread after thread on line this is what I found;
    I wanted to neck down my 6.5x55 Ackley Improved to a .224 neck, listed in P.O. Ackleys book I found a cartridge by DR. E.L. Arch this lead me to find the Vais cartridges! George Vais took a swede 6.5x55 case blew it out to an improved shape then necked it down to .224". I will need to pull the article to post velocities and bullet weights however I do remember superior tack driving groups were shown, Precision Shooting April 1998 is one printing. I think aprox 3800fps with 80 grain pills.

    A little off topic but I opted to build a 6mm-284 to launch 66grainers at +3900fps. just need to finish ream the chamber then off to the bench :D

    George Vais is a very good friend of mine an has built many tactical and long range rifles for me; his {6.5x55mm} wildcats are very good long range performers'..., known for there accuracy an high velocity. I had George do the work on my .22-250 AI only because at the time he was not turning out any of the .22 Vais with dies. As it stands now, George is about to head back to Greece this month do to health, which is very unfortunate, we’re loosing a great gunsmith.
