I load Speer Unicor 300 gr at 2200 fps in the 45-70 and it is just a little more of the same, but no deadlier than the 444.
A very good bullet. It holds together at that speed very well, and matches the trajectory of my .30-30 close enough not to worry about any difference to 200 yards. As for the .444, I would much prefer the 265 you mention over the 240 XTP. The new Speer "Plinkers" are Unicor construction, but I've not tried them at .444 speeds. They are doing pretty good at .44 mag speeds in a rifle, though.
