22-250, goldilocks twist rate

[7Miller]

OK, so I'm wondering what the ideal twist rate would be in a 22-250 to be able to stabalise bullets from 50gn to 70gn??
As I'll be wanting a tikka, because it's what I've always had, they come as standard with 1:14 but also have found a tikka 22-250 that comes with a 1:8 twist rate.
Barrel will be 24"

So to be able to stabilise well and shoot very accurately, is a 1:8 too fast? The 1:14, I guess is too slow for anything north of 55gn or anything too long?

So maybe I need to go semi custom route, tikka action, and get a 1:10 twist rate?

After your experiences, knowledge and words of wisdom please

I shoot 53gn Vmax from my .22 Creedmoor, with a 7.7" twist barrel, no problems, just not quite as accurate as the 75gn ELDMs, but we are talking 1/4 MOA difference, maximum.

You might be on to something there. A 10 twist should stabilise lead cored 70 gr bullets.
Tikka built a batch of 10 twist 22/250’s a few years ago for the US market.

I've seen tikka t3x rifles available here in 1:14 twist but also their website states they do the T3x Super Varmint with a 24" Barrel with a 1:8 twist. My "worry" is it may be too fast if I decide to shoot 50/55gn. Anything else would have to be a semi custom build on a T3 action. If I have to go down the semi custom route to get what I want, then I may as well scrap it and get a 22 Creedmoor built. I went for the 22-250 over the 22CM thinking it would be easier, (thus, cheaper), to get off the shelf rifle and brass etc. In reality though, it's not as simple as I first thought.

8" twist isn't too fast for 55gn, it just works.

I'd go with the Creedmoor option, plenty of excellent brass now available, good case life with Alpha and Peterson.

I had a 1-7/34 twist 22-250

Worked fine with 55gr Barnes ttsx

3650fps

Going to 22 CM just cause I am

Just built this 22” 22-250 1:8” on a tikka 595, for a customer, no worries about twist being too fast. Done .22 CM’s in 1:7 and reports on performance are very positive

I have an 8 twist 22-250 built on a Sako 75 action by Neil McKillop, shoots everything from 53gr to 77gr without any issues and I have previously had a 7.5 twist one that was the same.

S&L with 21" barrel and 1:10 twist shoots 69gr tmk accurate enough so there is no room for improvement without need of high speed even

I have a 1:9, very good with 69gn bullets but 75gn are very erratic
