22 Terminator 1-7 Twist

Just got the new 22 Terminator going with a 1-7 twist TF UM barrel.

It has a PSE stock I got a while ago.

I have been wanting to build a 7 twist for a wee while now to shoot the 90 Bergers with their .551 BC :)

http://i1004.photobucket.com/albums/...psfe8569b9.jpg

I was quite surprised with the velocity shown in initial testing & I think there is more in it with the 90 Bergers.

It is only 150-175 fps behind my normal load in the 22-243 & a heap less powder.

I can push the 90s beyond 3200 fps in the 22-243, but they have a nasty habit of self destructing mid-flight, the more heat the worse it gets :oh noes:

So 3100fps is a happy medium with the 90s in a 7 twist :)

That stock looks the bizzo!

Nice look rig - impressive speeds!

what is the case?
that's fast though. im sure it will open up rabbits well.

I was thinking about this today... is the 204 ruger case a necked down .223?
so you have basicly made the 204 back into .223?
I really am not sure, but whatever you have done sounds good. you know I shoot the .223 with the 80gr amax, at about 2800.... next barrel, if I had them doing 3000 that would be great!

.204 is a necked down .222 magnum case.

and isn't the .222 mag and the .223 pretty much the same thing?

The 222 mag is the parent case to the 204 but the shoulder is moved foward and angled to 30 degrees.

Na. 223 necked down is 20 practical, bit less case capacity

Done it, got the reamer, 22-243 imp goes a bit better than the straight 22-243 :)

No problem, do you have a good supply of .20 cal barrels ? :)

Waiting patiently for a 6mm & 6.5 Saum to be made.

Have a 204 Ruger barrel which might be spare shortly ;) assuming the couriers don't mess it up.

20 BRX ;)

.20-250 = 20 Terminator :cool:

is this the same as the 222magAI that you can use ( i read this on the net so taken with a grain of salt ) the .223AI dies that i have to partial size / seat bullets if i went with your Terminator or would i need new dies . . i couldn't find any drawings on the MagAI or your Terminator online

my idea would be to rechamber a .222R that is not needed to push the 50s a bit faster - is that something you do ? cheers R.

It is straight 204 necked out from 20 calibre to 22 calibre.

It "should" be "bigger" than the 222mag ai.

The other thing to consider is there is plenty of 204 brass around & no fire-forming required.

Just need a Hornady 22 seating die, a 22 neck die & a modified 204 body or full length die, simple really.

Yep can re chamber a 222, a few things to consider, mag length & twist rate.

cheers for that, sounds good .. . Rem700 SA and standard 1-14 twist . . . as i say my intention is to push the 50grn bullets faster but not wanting to go to the .22/250 sized case.

R.

@kiwiGreg how dose it compare to the new 22nosler

The 22 Terminator is about the same size.

Looks like the 22 Nosler load data is backed off so the AR15 can cope with it happily.

It might be an interesting cartridge in a bolt action, not sure about brass, die costs & availability ?

The 22 Grendel has more grunt for an AR 15 :)

Cheers mate

Was thinking it would perform a lot better in a bolt action

Hi Greg. What is the barrel length and load data for this velocity please?

I know Greg’s generous with the info that he posts on here, but you’re just taking the piss dude!

I apologize as i didn't mean to offend anyone. I am genuinely interested in this wildcat enough to build one but with little to go on i wanted to ask. I'm sorry i did.

What powder is that load using?
Thats incredible performance consider the amount of powder being burnt.
