Here is the 25-06AI load data provided by Berger for the 133/135 bullets. The barrel was 26” and the AI has more capacity than the standard 25-06.
The AI version definitely has a little more boiler room but with the QL model Berger used in that load data they're using a pretty shot 3.250 COAL which eats up quite a bit of that case capacity advantage the AI has over the standard so when I run the same 3.250 through a standard 25-06 at the same pressure same barrel length per QL there was less then 50fps difference.

In a 22in tube with their 135's 3.250 OAL and 59.7gr Magpro which per QL is 59,951psi 2927 fps.

Standard 25-06 same chamber PSI, powder, 135 OAL 3.250, barrel length, 2894 fps.

To your point the long 25-06 maybe isn't the best choice in a Tikka because QL projects a 25-284 with same bullet, same chamber PSI and same 22in barrel it shows 3000fps

That 270 WSM # sounds awful high, i'm pretty sure 7 WSM which was a bigger case were more around 81-82 grain h20?
I randomly grabbed a handful of ADG 270 WSM pieces of brass from the four boxes I had delivered the other day and new unfired they hold 79.5gr H2O. Average empty cases weighed 225.6gr I was going to measure the neck thickness but forgot. I'll try and remember to get that tomorrow.

I talked to ADG last week about their 270 WSM case capacity and the guy said it was a foul up on their end and I see they've already changed it.

Come on man...head stamps don't matter!
lol true they don’t but almost had an oopsie once when I was juggling 5.56/25-45sharps/6x45 because they were all 5.56 brass. Ended up getting mixed in together after a spill and had to sit there with calipers to confirm what was what. That was fun and subsequently I’m down to only 5.56s and a 25-45sharps.

Waiting on dies for a 25-35 ai. Fast twist, so keeping it slow (2800) for 75g vmax to not blow them up. Might try some 134’s to see how they work.

Assuming you had a 94 reamed out to the ai dimensions, or is it something more exotic?

I’m waiting to find a good condition 94 drilled for reciever sights. I shoot monos so would be limited to the 100gr hammer lever hunters .

Tc contender 1:7 twist so it can handle heavies. Going to try the 75g vmax on coyotes. Then some 134’s for larger game. Supposedly the ai version is the largest case capacity gain of any ai cartridge. Used 375 win brass to make cases.
