This should give you something to work with. Tested on Labradar
16" = 2375
18" = 2455
24" = 2590
Above speeds are an average across 3 shot groups with factory precision hunter ammo in 3 different tikka t3 creedmoors ive dealt with, all with factory barrels (shortend in the case of the 16" & 18"). Definately on the slow side compared to what the velocity on the packet suggests.
Assuming you have a 22" barrel, somewhere around 2550 will be a good starting point.
