I have a 5" Super BlackHawk and a 7.5" Super Blackhawk.
I like to carry the 7.5 when trekking the back country, grouse hunting with a smoothbore, picking berries, etc., but not actually back-packing. For back-packing I switch to the 5" gun.
The 7.5" really shoots out to 100 yards nice, and I took a deer with it once at about 125-130 yards. The deer dropped like the earth had been pulled out from underneath it. It shoots a 250 grain bullet at a true 1534fps. I've shot a zillion grouse with it too, with shot loads.
The main load for the 5" is a hard cast 300 grain bullet at 1300fps, but it also likes the Speer 240 grain FMJ. Shoots them both to same POA. I've taken a few grouse with the 5" too.
Just recently I got the 5" gun Parkerized. I got the gun originally as a box of rusted parts, and much of the gun was too pitted to take all the way down in order to put a decent blue on it. The parkerizing looks great, really dark grey, with contrasting black ejector rod housing, loading gate, and grip frame. It's quite "unique".
