I bought a Smith and Wesson that had some trigger work done by the previous owner. I haven't reloaded for it yet, but I was easily hitting a 6 inch steel plate over and over at 50 yards. I probably haven't put 50 rounds through it yet.
I've got a Ruger Super Redhawk in .44 mag. With my full loads, I can't keep a 6" group at 25 yds. The S&W will maintain a 2" group.
The Ruger has a 12 pound trigger, and the S&W has a target trigger and hammer that breaks at 3 pounds.
Pretty easy to figure out that the Ruger needs a whole lot of trigger work.
