I would not use the 240gr XTP unless its the 44cal. The .452 240gr XTP is a MAG and the jacket is super thick. They will be ok at high velocity and close range. Once the range increases they might not expand at all.
Out of the ones you listed i would use the 300gr SST and whatever sabot fits your bore best and shoots the best.
Harvester Smooth Black sabot for 45cal bullets 300gr and under might be a good one to try with the 300gr SST. The sabots they come with are MMP 3p-EZ and are probably pretty loose in that bore. MMP HPH-24 is close to the HSB sabot in loaded OD but slightly longer.

Shoot what is most accurate and one that you've had experience with.
That was so very helpful. Im sure the OP gained a wealth of knowledge from your post.
