Anyone have any real world velocity differences between these two with 77gr tmk’s and the same barrel length?

I am wondering because I’m going to buy a Tikka T3x stainless and I haven’t decided if I should just buy the 8 twist 22-250 model or spend the extra money and rebarrel to 22 creedmore if I’m gaining a significant amount of velocity.
Only you can really decide but for me If it was something as simple as changing from one powder to another to gain 150-ish fps IMO that would be significant enough to make it worth doing but to go to the expense of rebarreling from one to the other to gain that extra velocity it would not be worth it.I am wondering because I’m going to buy a Tikka T3x stainless and I haven’t decided if I should just buy the 8 twist 22-250 model or spend the extra money and rebarrel to 22 creedmore if I’m gaining a significant amount of velocity.
How does the 22 Creed handle light bullets? Even with similar case capacity and caliber they seem to fill entirely different niches. I’d imagine it would run into accuracy issues with throat geometry like it’s siblings when going light for caliber, and also overspinning/ blowup when stepping on the velocity of light varmint bullets at 1/8 twist.I think we're in a transition period at the moment - 20 years from now, I suspect .22 Creed with have almost entirely replaced .22-250 in new factory rifles, with .22-250 also becoming more and more something that "granddad" used. Eventually becoming more obscure, like .22 Hornet. Which is/was a perfectly fine cartridge, but .223 has almost entirely eliminated it in the category of things it was used for. There are a lot of advantages beyond velocity the .22CM has over .22-250 as well, including things like brass availability (as mentioned above), ease of cartridge conversion, etc. None of this detracts from .22-250 really at all, but if I had to choose like you're doing, I'd probably go .22 Creedmoor.
When you say "throat geometry" are you referring to lead angle or freebore? I don't think they're use a different lead angle for a 22 Creed then they would a 22-250 and if you're referring to FB, well, all factory rifles regardless of twist rate have a pretty healthy amount of freebore and I don't see that changing anytime soon.How does the 22 Creed handle light bullets?

That’s basically what I’m saying, depending on the barrel they can choose to go either heavy bullets fast-twist longer free bore, or light bullets slow-twist shorter free bore. I’ve heard the other creedmoor calibers don’t do well with light bullets and big jumps to the lands so I’m curious if the 22 creed is able to pull double duty. This is all in regards to the original quote of the 22-250 fading away because of the creed.When you say "throat geometry" are you referring to lead angle or freebore?

I think if someone buys a hot rod 22 cal like either the 22CM or 22-250 with an 8tw barrel they're doing so because they plan to shoot heavier range of bullets and if they ever decided to try some light ones IMO it's one of those buyer beware things no different then if someone bought a 14tw 22-250 to shoot lighter bullets then gets a wild hair to try some heavies it wouldn't go well. As they say, these things are like tools and for the best results use the right tool for the job.
What have you shot out of it and what were the velocities?I got the tikka 22-250 with a 8 twist. The barrel is slow as hell but shoots very well. I’m in the same boat as you with the 77 TMK. When I find some and get back home in a few weeks, I’ll load some up and report back.
Thanks! It would be much appreciated.I got the tikka 22-250 with a 8 twist. The barrel is slow as hell but shoots very well. I’m in the same boat as you with the 77 TMK. When I find some and get back home in a few weeks, I’ll load some up and report back.
That’s exactly what I’m doing. I managed to find some Lapua brass last year but I was planning on using nosler or hornady.Since id say most agree that it’s very hard to beat factory Tikka barrel accuracy what I think I’m going to do is just run the factory 8 twist 22-250 barrel until I shoot it out or get tired of it then rebarrel to 22 creedmore. I think it’s going to be very hard to beat unless I did a custom chambered barrel rather than something like a Preferred pre fit (which is what I planned on doing in 22 creedmore) or a rechamber job on the factory barrel.
Also since Lapua stopped making 22-250 brass what is the best brass option atm?
After doing an extensive google search I can’t even find 22-250 brass rn of any brand… maybe 223 is the ticketThat’s exactly what I’m doing. I managed to find some Lapua brass last year but I was planning on using nosler or hornady.
