I have a friend buy one and he had nothing but trouble trying to sight it in as it is not a true ballistic scope, as with this one it if I can remember right the testing done with this scope was with a 300gr. bullet using a magnum charge of 150gr. of Pyrodox Pellets. So if you dont use exactly what they do for a ML load,then you have to (ESTIMATE) where you should hold for the longer shots. And if you have to estimate, then why not just buy a regular scope and do what you have been doing. That's why this scope is on sale and as cheap as it is. I know it's more money but I purchased a Leupold Ultimate Slam ML Scope (almost the same as the Nikon Omega but better,IMO...With this one, the Leupold,it has 3 different settings, a 2 pellet setting, a shot-gun setting and a 3 pellet setting, but with this one also it was tested using a 250gr. Bullet and a 150gr. charge. but it also compensates for different settings,,2&3 Pellet &shotgun. So you at least have a few more options, as the lower long range reticles move farther apart or closer togeather depending on what charge your using.But what I found to be the least thing I liked about these Ballistic Scopes is ONCE SIGHTED IT FOR WHAT YOUR USING YOU HAVE TO SET THE SCOPE FOR THAT SETTING AND STAY THERE. SO SAY IM USING A 3-PELLET SETTING, THIS IS 9-POWER ON THE SCOPE, SO ALL MY SHOTS HAVE TO BE AT 9 POWER. SOMETIMES 9-POWER IS WAY TOO MUCH FOR THE SHOT, BUT IF YOU WANT THE SCOPE TO DO IT'S JOB THEN THAT'S WHAT YOU HAVE TO DO. The scope is mainly intended for shots FROM 150-300YDS, and in most cases we dont shoot that far anyway, and most of us are just kidding ourselves if we think we can set the scope to the 300yd or even 200yd setting and properly and humainly harvest a animal. Yes, I purchased the Leupold, but mainly for long range shots on Coyotes, because I HATE THEM! My Hunting ML I use for Deer has a Bushnell Dusk to Dawn 3-9X40 and it cost $89 and preforms flawlessly for a fixed reticle scope.For the extra $20 I'd have bought the Bushnell......Let us know what you think of the scope when you try it out, you may like it, this is just My 3cents. Ron p.s. I do like the Leupold U.S.ML Scope, but it does take some work and patience.
