Congrats on that fine looking muley and also on the shooting. 75 yards and 65 yards are getting out there for a revolver.
I have been a wee bit disappointed in some of the handgun shot critters that I have taken. One that sticks in my mind is a 2x3 young mule deer buck at around 40 yards with a SigP 226 in a .40 pushing a 180g cast slug at 1164fps over a chronograph. Hit him mid ribs but he still ran uphill another 120 yards before I could finish him at 25 yards.
I'm thinking like you about upgrade the power factor for this handgun hunting stuff. Next time out it's my Old Vaquero 44Mag on the hip.
