MV of Ultramax Cowboy Ammo from a 20" Barrel
Posted: Wed Mar 21, 2018 10:44 am
I'm shooting Ultramax .44 Mag Cowboy ammo from my Browning M92 with a 20" barrel. Ultramax states on their website that the MV is 710 fps. Although they don't state the barrel length, I'm sure that this MV is from a revolver with a 6" - 7 1/2" barrel. Can somebody give me a ballpark figure for the MV from my rifle?
Thanks,
