Is the weight worth it

I don’t doubt that you can score hits on target out to that distance but I wonder if the bullet still has enough velocity from the short barrel to expand or fragment at those distances.

It’s been a while since I checked the ballistic calculator on my given ammo but I seem to recall that it slows below the speed necessary to fragment somewhere around the 200-225 yard mark when fired from a 12.5” barrel. I could be mistaken though.

Maybe. But the bullet will still make enough of a hole to cause a notable leak in the hydraulic system. Add to that, if a foe were to take offense at having such a hole put in their hydraulic system, they'll have to have to cover that 300 yards or so to register their complaint, risking more leaks being placed to greater effect.
