I have the Leupold Ultimate Slam MLer Scope and LOVE IT......BUT I have found out that I DONT NEED the S.A.B.R.E. I used it set to specs for the load recommendations and it worked well. The Leupold has more settings than the Omega, with the Leupold you can set your load to a Shotgun, a 20 Guage Shotgun or a Magnum Load of 150 grains, these settings are compareable to some other blackpowder loads but I cant get to all the specifics now as Im not going to look into it

But the Leupold is much mor User friendly than the Omega as the Omega you can only set your Load to one and only one setting.
So to the point I just sight my Leupold USML Scope to sight in at 2" high at 50yds and Im dead on at 125yds and 4" low at 175yds. So I can just hold dead on, middle of the lungs from 50yds to 175yds and Im in the kill, anything under 50yds I just hold heart area. This is much more simple than in the moment trying to decide where to hold when I can just hold dead on and be good, if it's a close shot I just have to remember to hold on the heart.
I hope this did'nt confuse anyone but a fixed scope is much better to me than one with a BDC, less to think about and easier in the moment. But if you shoot a 250gr bullet and either a 100 or a 150gr BP Load or a 12 or a 20 Guage and want to be confused but still be on than the Leupold USML scope will be a good choice, better than the Omega for the exact same money as it does way more.
I like to aim, hold and shoot, but if I wanted to think, hold and decide and shoot I;d use the SABRE more.
