The thing with Cowboy guns is you want to shoot the side matches too so you get a derringer, then you get a single shot for long range, then a lever big bore for the occasional long range bit bore gong match etc. These are all sold now. Arthritis has ruled out cowboy shooting. Not cool to drop a gun in a match. Great sport and fun.
The three rifles are a Marlin 1895 Cowboy in 38-55 and a Browning Traditional Hunter in 38-55 both super accurate. Added real sights to both. I could shoot long range with these because I upped the bullet weight. The Browning shot a 330 grain Hoch Nose pour bullet and I found a 300 grain Saeco mold that made bullet the Marlin liked. I figured the twist rates and put the biggest bullet in that the barrel would stabilize. Accurate Arms 5744 powder and also Blue dot makes a great rifle cast bullet powder for 30-30 and 38-55.
Also a Marlin 1894 Cowboy I had a guy convert to 38-40 with a Green Mountain barrel. Odd thing about this gun is I bought it used as a 45 colt gun and it never did have the usual Marlin checkering, came smooth.
The 73 is an Italian clone in 38-40. Most folks go for the bigger rifles but the short carbine gun is the sweet one for fast shooting. I removed the finish, stained it and refinished with Plinkingtons oil from Brownells. Had a lady cut the checkering for a little added class.
The American arms derringer was in 32 mag and although you would not guess, the darn thing was accurate. Both barrels registered really close at 7 yards. Slow for competition because of the rebounding hammer. Gunsmith polished the SS and added Ellen Hunting real stag trips so I could hold on to it.
