Likely BC and velocity of steel cased 145gr FMJ?

[Snakum]

I have a couple of cases of Barnaul steel-cased 145gr FMJ ammo and want to work up 'starter tables' for it before heading out to shoot it in my Saiga SDM rifle. I don't have a chrono yet and couldn't find a G1 BC for a 145gr FMJ. Anyone take an educated guess what my starting numbers should be?

It'll be shot out of a 21.8" Saiga .308.

I stand by to be corrected, but:

Bear .308Win/145gn is advertised as 2754fps.

For Bc, I would try the neighborhood of M80 ball, using G1=.393 and G7=.198 (or a bit lower...)

Thanks much. Got it plugged in and will test it next week to build the table.
