It is amazing what you can tell about a person's experience by reading their posts. In cowboy action shooting, accuracy is not really a big deal, speed is. You are shooting at steel targets that are maybe 12 to 15 feet away, so a gun that shoots a group of 2" is no big deal. Yeah, most Ruger's in 45 Colt will shoot low, but once you figure out which weight bullet you are going to use and file a bit on your front site, they do just fine. Speed is everything in cowboy action shooting, so a light bullet and light powder charge is everything. Most experienced shooters use 38 special and 32 H&R's, down loaded with light bullets and powder charges. Marlin rifles are really good, but 73's and 66's are faster because they can have short stroke kits installed, again, speed is the name of the game. Trimming seconds makes a difference.
