Howdy, thought I would chime in.
Newcomers to Cowboy Action Shooting often want a revolver chambered for 45 Colt, because that is what the old timers shot.
Then they go down the rabbit hole of trying to make the cartridge recoil about the same as a lightly loaded 38 Special. Difficult to do because the cavernous case of 45 Colt does not perform well when loaded with just a few grains of Whiz Bang.
Let's see how well the High Road is doing today at posting a few of my photos.
This pair of 2nd Gen Colts are my Main Match CAS pistols. Both are chambered for 45 Colt (Not 45LC or 45 Long Colt, there is no such thing).
The 7 1/2" barreled one at the top shipped in 1973, the 4 3/4" barreled one at the bottom shipped in 1968. A previous owner tried to 'antique' the short barrelled one, hence there is just about no finish left on it.
Another pair of 2nd Gen Colts, both chambered for 45 Colt. This pair are in immaculate condition. The one at the top shipped in 1973, the one at the bottom shipped in 1963.
Yes, loading 45 Colt with Black Powder tends to be expensive because of how much Black Powder is needed to fill the case. I don't even remember how much BP cost the last time I bought it, but I can tell you I can only get about 200 rounds from a pound of powder. Using my favorite Smokeless Powder, Unique, I can get 933 rounds from a pound of Unique.
Is shooting 45 Colt with Black Powder fun? You tell me. Here is my 4 3/4" Colt at full recoil.
Let's see if the photos come through ,
