Boy; I havenít heard of Super-Vel for twenty years or more though I still have a box of 45ACP somewhere hereabouts. They achieved those velocities with some pretty high pressures and lite bullets. I think that it would not be advisable to risk a nice #29 though it would be unlikely to damage it. Why not take the ammo to the next gun show and get a trade. You will likely come home with a lot more ammo! For deer hunting, I should think that the weight might be a bit lite, as 280 300 grain seems more appropriate!
I just looked up and there are a number of boxes of Black Talon on top of the cabinet behind me, and those are now going at quite a premium. I reckon that I should do the same with those!
