I have a Nikon Omega on my Endeavor and love it. Very easy to use once you figure out where the circles are going to put the bullet. If you plan to shoot the exact load the reticle was designed for, then that's fine. But if you're like most smoke pole guys, you'll wanna play with different powder charges and bullet weights. If that's the case, it'll take some testing to tell where the marks on the reticle will place the shot.
