I'm trying to find out what the muzzle velocity would be in my .44 magnum Marlin 1894. I'm using Hornady 200gr. XTP in it. Their website lists mv at 1500 fps but their test barrel is 7.5". What would it be out of the 20" barrel on my Marlin?
And another question, does anyone know the BC for Federal's 180gr. .308 Powershok? I can't find it on their website and I'm trying to get a drop chart for it with a 100 yard zero. Federal gives a drop chart but it only goes to 300 yards with a 100 zero so I was going to use the calculator on Hornady's site but need to have the BC for that.
