Try actual bullseye pistol. You have the gun for it--the heavy barrel 41, presuming it's tapped for optics. The field barrel or the Woodsman would be better for steel, you want less mass up front. And you already have the ammo. Not giving indoor BE a shot would be a crime.

10-ring on a 50-foot slow fire target is .9", btw, just a little bit smaller than a quarter. You can hit it, so long as you don't try to hit it.
