I personally have none of the three, but being that Hornady loads for the 450 Bushmaster, it might be easier to get the loaded ammo at more places. The problem with the Bushmaster is that they use a special powder that is not available to the public to get the published velocities (or so I have read).
The third of the group uses the same bullet that the 45-70 uses which opens up some reloading choices.
If I was going to get one, I would look at bullet choices and see which was the most available and had a bullet choice that I could afford to shoot. Many guys get one of these large calibers and run 40 rounds through them only to find out that they cannot afford to shoot them and then they sell them.
YMMV
