Leupold GrandSlam Shotgun muzzleloader Scope

I purchased a Leupold Grandslam shotgun/Muzzleloader scope last year, however I cannot find the manufactures book that details the different markings on the power ring selector . It is a 3 X 9 scope. I understand the 3, 4 and 9 power markings but I don't know what the two dots and the shotgun shell markings are for. I also know those markings have to do with whether you shoot two pellets or three pellets out of your muzzleloader but I don't understand how they are used.
I have been on Leupold's website but I only found the basic scope directions and not detailed instructions for this scope.
The scope I mounted on a Savage 220 20 gauge shotgun.

Any help would be appreciated.

Thanks Navigator

Re: Leupold GrandSlam Shotgun muzzleloader Scope

Simple, if you shoot 3 pellets you put the scope on those marks and your gaps are the right distance apart to account for the drop..2 pellets the velocity is less therefore the gaps are bigger, the shotgun drops are even bigger therefore you need bigger gaps...I bought one when they first came out and tested it with the 250 shockwave, they are right on the money with the amount of drop..never checked the shotgun obviously but I'd bet they are perfect. Sit at the bench and look at the difference the gaps show at all three settings, that's the only way you'll see it... They don't work at just any point of adjustment only at those three marks...great scope, right where the big thick crosshairs meets the thin is dead on at 300 yards... Mine is on a t/c triumph..shot mine with 777 pellets also, never checked anything else.

I see your using it on a rifle, I'd set it on 9, sight it in at 100 yards dead on, then using a big piece of paper shoot a shot without changing anything and see how much higher the bullet hit at each mark, easy to figure out then how far each dot will shoot dead on..

Thanks 6-Dasher for the reply.

I am sighted with just using the reticle dead on at 100 yds, 1 1/2" high at 50 yds and 6" low at 170 yds. If I use the first dot at 170 I am back on.

Once you dead on with the cross hair it's easy to see how much each dot raises the bullet at 100, from there you can easily figure our at what distance each should be about dead on...I'd imagine that's a long way for a rifle cartridge because of how big the gaps are...lots of people think the gaps are right at any point from 3x9 , but they are only correct at each of the three points...hard scope to find these days, glad I got one on my muzzleloader.
