Xcutter,
First I only have a 44 mag in a revolver so I am limited in the round in a rifle platform... Anyway
If you don't hand load you might have found the best, especially if they shoot well out of your gun. For what its worth, I have tried the Fusion's (240) out of my Ruger Super Redhawk and they did pretty well. I have a buddy who tried the Hornady Flex tips (225 Gr???) in his levergun and they had a lot more muzzle blast and that they didn't perform as well as the jacketed soft points on the deer and antelope he shot. When I was first shooting mine I bought winchester white box and they were the dirtiest things I have ever shot, the American eagle aren't much better. The Fusions seemed to be cleaner and also grouped better. Since then I have been reloading and found a sweet spot with 2400 powder and the Hornady 200 grain bullets.
If you have a chance I would suggest looking for a little lighter bullet to try, Say a 180 grain federal or remington. Idea here would be to see if your rifle grouped these any better. They might give you a little more range, but you will give up a little energy as well. Could go heavier too, but unless you are in bear country I think the sweet spot is 200-240 grains for the .44
just my .02
