I'd prefer aa-4350 if I had to choose one of the three.
I'm running H-4831sc in my 308's it cleans up the trash when you get close to 50-k and a little Dacron filler gets you there with a tick less powder.
part of the trick here is getting the boolit started into the barrel [straight] and then accelerating it to speed.
if the hunter powder is on the slow end of 4350 I'd go with it for a few rounds, use the filler and a warm primer to help it burn a little more efficiently.
if it's super dirty and I wanted to still use it I'd trickle 2-3 grs of red-dot in the case first, then the hunter and top it off with a filler to keep everything in place if necessary.
if you are trying to push the velocity envelope you are going to have to go off the grid a little.
