Have you tried shooting different ammunition in the old girl? I would be more concerned with getting it on the bull than any worries about how the finish has faired after all these years.
It looks quite well for what it is, and far better than most that are similar.
Best,

All I have is the HSM as I wanted relatively low recoil and a non-jacketed bullet.
Note: the sights on this gun are not what anyone would call "target sights." My guess is that with a target having more white I will be able to hold a better zero.
