I've got a 20" Rossi in 45 Colt. The action was pretty rough when I first got it many years ago but has smoothed out with use. It loves heavy Ruger only handloads and will knock **** out of a deer. I keep shots inside 100 yds due to my poor eyesight but it will group around 2" @ 100 yds with younger eyes doing the shooting.
With the 20" barrel it is a joy to carry and makes a good deep woods gun. One of the main benefits to lever actions for SD situations is they can be top loaded while cocked and chambered. Even with Cowboy loads it is a formidable gun.
