It is fun and very challenging....
This is a the front sight David Clements made up for my Freedom Arms 83 .41 Magnum...
When Mac and I were shooting last fall we were using S&Ws. The red ramps can be used much the same way, just hold up parts of it.
Mac shooting out across the lake...targets started at 200 and worked out to 550.
Shooting from the porch of his cabin at a 100 yard gong...
..and you don't need a "Magnum"....although Mac was using a .44 Magnum and I a .41 both had handloads under 1000 fps... Big bullets help because they are easier to see when they miss the target as they'll throw up dirt a .35 won't...
