22-284 wildcat?

I am trying to resarch a crazy fast wildcat in 20 cal or 22 cal. I have found some info on a 22-284 wildcat with a 60 grain bulet going 4100fps or a 75gr bullet traveling 3800fps. I know what you are thinking but, I read in my old nosler mannual that they have safely tested there 22cal 55gr noslers to 4900fps.
I kinda think a 22-284 would push a 60gr faster than 4100fps am I wrong? How is the accuracy? How is the Barel life?
If you have a 22-284 or something similar don'y be shy.

Thanks Gabe
 
At those velocities , barrel life would be pretty short . Sounds cool though !
I have been kicking around an idea of a super fast 25 caliber for a few years now . Barrel life on them seem to be short too but I still want one ! Maybe I'll just buy two barrels and have them chambered and threaded at the same time , then I would have a spare .
 
And you would be just wasting powder really... why not do something like say 20PPC that will push a 50gr bullet at about 4250fps!

One of my very good friends and pdog shooting buddies had one (.22-284)built the year before last, with an eye toward a 1K yard pdog rifle. A year and a half later, and he's still trying to work up a load for it. He's not lacking in handloading experience, but apparently this is one finicky round to load.

His best accuracy to date has come with loads running 400 fps less than what he knows he can get from this rig, and even his fastest loads are considerably less than what he'd been told he could expect from this chambering.

He also says that forming the brass for it has proven much more difficult than any wildcats he's dealt with to date.

edit: We did try some 1K paper punching with it though. His "accurate" low-speed load grouped 5 shots into 6.75", 8" below desired POI. That's pretty darned good.

With a 60 grain bullet, his "accuracy" load was running in the mid-3600 range. Heck, I get 3640 with a 75 grain VMax from my 6mm Rem, and it'll group sub.2 when I'm on my game.

He has had it up to nearly 4K, but his accuracy was around 4" at 100 yards.

He's still searching for "the load" for it, but it's looking like he'll have fired 500-700 rounds finding it...if he ever finds it.

He's still not willing to give up on the rig, but I figure when the barrel is finally shot out, he'll not have it rechambered in that round again.

edit: It seems to me, when I really think about it, even if you got a 60 grainer to 4100 fps, that's a heckuva lot of powder/throat wear for marginal gain over more conventional chamberings.

You will use up most of the barrel life working up a load. It is doable if you will only use it to shoot called critters and keep spare barrels on hand. The secret to using these severe overbore chamberings is to always have spare barrels ready to screw in. If you have spare fitted barrels, it only takes a few minutes to change a barrel.

My 6mm will push a 55 BT almost 4100, it averages 4085 over 5 shots, even with that I am afraid to look down the barrel with a bore scope. It does shoot good, 5/8 or so @ 100 yards.

I read an article on the 257 STW years ago. Sounded like alot of fun, but barrel wear was pretty bad.
 
One of my calling buddies has been shooting a .22-284 for many years now. It's his main rifle that he uses when night hunting. That thing is awesome. His has a 30" barrel and he is shooting the "old" (no longer available) Berger 64 gr. Match at over 4000 fps with superb accuracy. It's a coyote death ray.

I've been using a .20-250 off and on for a little over a year now. It has a 25" barrel. My working loads push 40 gr. bullets at about 4250 fps or so. The bullets I've been using most lately are custom 38 gr., at about 4300 fps. All with excellent accuracy. I don't like to disagree with Jack, but I've worked up good loads for over half a dozen different bullets in it so far, and the barrel still has plenty of life left in it. Indeed, for it's intended use, the barrel could easily last another 10 years. And as mentioned above, my buddy's .22-284 has already been killing coyotes for 10 years and undoubtedly has quite a few years left in it.

There was mention of a big .25 made too. The same friend who has the .22-284 had a .25 WSM made up this last year. Wow! That thing is amazing. It slings 100 gr. bullets at 4000 fps and shoots them into tight little bugholes. Very neat rifle!

DAA,

Speaking of Blaine,How's he been anyway?It's like he dropped off the face of the Earth or something,At least as far as the internet goes.

How have those Unmussig bullets been working on the coyotes?I have been thinking I might call him and order something similar for my .204 ruger.I really like the 35 grain bergers,just want alittle better B.C. Didn't you say the ones you're shooting have a B.C of about .260? That would really extend the range of my .204 a bit. Thanks

Good Hunting Chad
 
I bet that the 22/243 (middlestead) would equal the 22/284 with a whole lot less powder.

I have a friend that is shooting the 22/6mm Rem with amazing accuracy with the 75g V Max at 3800 fps.

I shot the 22/250 Ai with a 27" Hart barrel shooting the 65g berger at 3700 fps which was unreal accurate, and I considered this a max load for the gun with the brass needing full lenght sizing after each firing loaded with Win 760. I am sure that N550 would have been a better powder for the combo, but when a load works...don't change noth'en!
 
There's an article in this months American Rifleman about an Army Surgeon who built a .22-6mm AI. I think it said he was pushing 80gr bullets 3600fps with a 27" Lilja barrel. Shooting 2" groups at 500 yards.
 
Has anyone heard of a 204-6mm?

How is the barrel life on the 22-6mm? I loaded a 6mm with a short barrel around 55g 4000fps. The barrel got realy hot after a few shots. Maybe a fluted bull barrel would make a big differnce in heat.

Does anyone know of a good wildcat site with load data?

Thanks Gabe
