terminal ascent

Has anyone tested the velocity with the 26 in Barrel Hells Canyon with 200 Grain Federal Terminal Ascent? I'm trying to determine the difference between the box velocity which is 24 in barrel and what it would be out of the 26 in.? I don't have a chrono to test so hoping someone else has? Thank you,

I just realized that the Federal Premium website does not feed into ammoseek. Prices are not cheap, but there is quite a bit of selection available over there in popular hunting calibers. I just picked up 4 boxes of 200 Grain Terminal Ascents in 300 WM. It's been very hard to find this...
