Custom .22 hot-rod need opinions

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

Re: Custom .22 hot-rod need opinions

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

Re: Custom .22 hot-rod need opinions

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.

Re: Custom .22 hot-rod need opinions

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?
