Here's another light bullet for the .444, Barnes lists the 200gr XPB as 2333fps from a 15" barrel, it being a pistol bullet, but some of the fellas at Marlin Owners are shooting it and the 225gr in their leverguns, 2400fps would be a conservative estimate for the 200gr, 2300fps for the 225gr IMO, but it may not shoot well being .429" instead of the usual .430". Notice the energy level drops below the accepted 1000ft/lbs generally accepted for deer at just past 200yds, same for the .4295" Sierra 210gr.
