I always liked the 270gn Speer Gold Dots in my 444 Marlin as well. In my Marlins 22" bbl, 45gns of H4198 produced a 17 shot average of 2149 fps. The same powder charge with 265gn Hornady produced a 10 shot average of 2157 fps. Recoil off the bench was always tough, especially since those big bore Marlins have no recoil pad to speak of.
