Being the owner of a Winchester M53 in 32-20, I would have to be very careful bringing a S&W 32-20 into my collection. The rifle loads are much hotter and most certainly would blow the S&W up.
I had this problem years ago with my Colt SAA 44-40. I loaded my ammo to max in my late M92 for deer hunting and painted the rims bright orange. Just one of these would have blown that SAA all to pieces. My hand with it. BTW, that is a real nice revolver. Keep it and enjoy it. Big Larry
