Strelok Values- Sako Gamehead

[slickalaus12]

Hey guys,
I am noob so forgive the question if it's bad. I am looking to punch in values for Sako Gamehead (129h) ammo for 6.5 Creedmoor. For some reason even Sako doesn't have the info I need to plug into Strelok as they don't even have the 6.5 creedmoor gamehead ammo on their website anymore. I obviously have the velocity, and I am assuming the G1 value is 0.471? I have .264 for bullet diameter, any help on length is appreciated

Can't find that one anywhere. Only way to know for sure is pull one and measure.

The unknown length calculation for Berger's twist rate calc is bullet diameter x 4.2, so 1.1088" in this case.

Anyone tried the Sako 156gr deer head in 6.5 creedmoor ? How would it compare to the 140 ?
