I sometimes think folks over think stuff. Flip your question around. What wouldn't a 210gr. Silvertip work on? The worst I see is that it might give a different aim point from your other stock. You might want to keep it for someone who is learning big guns. The money you put into it is gone. They only really cost to you is replacement cost. And you will replace (reload) them with what you want. So shoot them. Use them for S.D. if you want. Do you have a snub nose .44? They are fun, and the light rounds are better with the short pipe.
I remember when I was first getting into shooting (only 7 years back or so) and a place was going out of bizz. I lamented to a buddy that the only ammo they had left was a bunch of S.D. .44mag rounds. I told him I just wasn't upset with that many people to justify buying that much s.d. rounds. He told me I just needed to get out and meet more people. :-(
So, shoot those rounds and re-load that brass. Or pull the bullets, reload, and try to find a home for the others.
