Lefty, I hope to do a .030 freebore 6 XC this Spring, #5 Contour. I am going to make the brass from Lapua Palma brass and will have a .400 long neck in the chamber. Will throat for the 87's to be .020 above the shoulder neck junction. I am hoping to shoot the 87g V max at 3400, but it maybe a pipe dream.
22 creedmoor or 22 250ai

@ Vince,..
I'm kinda Lazy,. Norma 6 XC Brass, Forster Dies and usually, StaBall 65 Powder, "Thrown Chg's",.. get's it, DONE, for Me !
Yes that's, a Fine idea,.. BUT too much "Work",.. IMO !
My $2,300 Criterion "RemAge" Semi-Custom, Rifle, already shoot's better, than I can !
PS; Watch your barrel Twist as, the 87 V-Max, would NOT shoot, Good "Repeatable" Group's, for ME in the 1-7.5 Twist.
I ended up using, 80 gr Berger FB Varmints and 95 gr. Cl hunt's @ 3,200 fps for, Sage Rat's.

These are the 25 flavor, but cases are the same.
25CM vs .250AI (parent case to .22-250 obviously)

I'd try, a 1-10 or 1-9 Twist Barrel for, the 87 grain V-Max or, Berger 87 gr. H-VLD's ( Both shoot Awesome, in a 1-10 twist )
Flat Base 80 gr Varmint Bergers, "BugHole" if not driven,. "Crazy Fast", in My 1-7.5 tw, Rifle !
They chop Sage Rats, in Half, but NOT great, "explosive",.. Aerobatics" ( oh, well ! )
I have my, .22-250 with, 50 gr V-Maxes for,.. THAT !

The 80g Bergers did not knock big holes in coyotes either, I went with the 80g Sierra Blitz BT for that.

22 Creedmoor seems to be a very popular cartridge these days. I'm about to send off a Tikka action to LRI to have 2 K&P sticks cut and chambered for it. Thinking 0.100" freebore with 1:7.8 twist to shoot mostly 70-80 gr, but neither is set in stone.
I wouldnt do a 22-250 ai until you can get lapua brass. The 22 creed has great components and no fireforming. I have both rifles, the 22-250ai I shoot 50 grain bullets and the 22 creed I shoot 85.5 bergers.

I have both - the 22-250 AI is a 1:8 twist while the 22 Creed is a 1:7.5. Either cartridge makes quick work of varmints and predators. I've also killed antelope and deer with both. The edge goes to the Creed for available components and even factory ammo options (Hornady, Mead ammo, Copper Creek, Unknown Munitions, etc).
Why not build a standard 22-250 if the max will be 400 yards?
36gr max in a 22-250 AI? I load 36gr of Varget in my 22-250 with room to spare.
22-25
22-250 ai components are just as available, just get 22-250 brass and fire form. If the twist is the same you're not ever going to notice a difference varmints won't complain either! If you want to run lighter bullets go with a slower twist. If a gun shop is trying to persuade you I'd be going elsewhere. If your going the custom route your gs should be listening to what your wanting not selling his idea on you. Fast twist and heavy bullets have their place as do slow twist and light bullets. Depending on your location and ranges and critters. Here in western NY my 22-250 has always killed with authority until you get into heavy pelts and larger older coyotes. Then the 22 creeds take over in the 70 grain range for me. Strangely enough the lighter bullets out to 300 yards in 22-250 seem to have the edge on whitetails than the creed does. I've had several of both calibers and still have one of each. I'm debating an ultralight 22 creed or 22-250 ai with a 10 twist barrel for critters and deer
I was in several Predator Clubs in S. Ca. There were a couple of dozen of us that shot the 22/250 AI with 12 and 14 twist barrels. Back then, Rem and Winchester brass is what we used, with loads with the 50's at 4150 and 55s at 4050. Accuracy at 200 yards was 1/2" with our 3.5x10s and 4x14s shooting 55g Sierra and 55g Noslers with Win 760.

..standard old fashion 22/250 is more than enough for all varmint hunting...why drive yourself nuts and expense for overall very little gain, especially for hunting purposes.
I built this rifle when I was dabbling in f class shooting, was many years ago now. I ran 105 a max bullets thru it and it shoots great. Im still a rookie with it tho, i have only 300 rounds or so thru it. Then i ended up moving and my f class shooting was done. I was thinking id try something different. I was just thinking that a 69gr tipped matchking would be awesome out of a fast 22.
I have nothing against the 6xc ,I just have looked at it everytime I went into the safe. I kind got bored with it. I'm probably going to tear it down and sell the whole thing but the action and try again. Maybe I should reconsider changing calibers because I have everything for the xc. Not totally sure what route I go with.
Frank, the 22/250 AI gets 200+ fps over the std 22/250, supurb accuracy at those speed levels also! I fire formed cases while killing coyotes when I lived in Az. Fire forming load was a 55g Sierra/Nosler at 3850 fps(1/2"-5/8"), formed load was 4050 fps. The 60g Berger in a 22/250 AI 12 Twist is a load worth building a rifle around, 3700-3800 fps.
As your shots on coyotes get between 250-350 yards, those extra 200 fps pay off.
