I have a 1986 Ruger Blackhawk 45 Colt I got used for $300 in 2004.
I have fired one shot in 18 years.
24 gr H110, 250 gr JHP... the same as for my other 45 Colt revolvers and rifle.
Recoil caused the sharp edges on the back of the hammer cut into the web of my hand.
So far I have not got around to taking the Ruger apart and finishing the machining.
