I really appreciate everyone taking the time to respond!
I will take it for face value, make a few test shots and hopefully put some meat on the table this year!

Thanks again!

if anything, aim a tad low. Dead on should be fine. I have the same gun and using it for the first time this year. Just wondering what slugs your having good luck with. Hornady SST's and Remington Accu-tips don't group worth a damn out of my gun. Too high of velocities I presume. tried Remington Copper Solids 2 3\4" 1oz sabots at 1450 and they seem to do the trick. Cloverleaf group at 75 yards, was very impressed

Or if you can see your barrel sight use it instead. At closer ranges I just put the bead where I want it and everything's fine.

Dead on, but you don't know if you are shooting on point of impact if you don't shoot a couple first..........

Don't get confused on the "being up in the treestand 14 feet" part.

The difference between the true horizontal yardage and the direct line of sight yardage is .53667 yards! i.e. if you were on flat ground it would be a 20.53667 yard shot, vs. up in the tree it is a 20 yard shot.

I agree, my calculations second this opinion. A fifteen yard shot would be almost the same - dead on if sighted in at 100 yards.

My calculation was specifically relating to the "being up in a tree 14 feet".

To truly calculate where the bullet would strike at 20 yards you would need to know how high the scope was mounted above the barrel and what the bullet trajectory is.

Since the scope is above the barrel, at the initial firing of the bullet, it actually climbs rather than falls since you have your barrel pointed just a tiny fraction up. Generally it peaks in the 50 - 60 yard range and then would start falling again to get to the targeted sight in range of 100 yards.

Based on my limited knowledge of shotgun sabot ballistics I would think that at any point in that 100 yard trajectory, the bullet would never be more than 2" from it's aiming point. As it exited the barrel it would be 2" below the aiming point, then it typically crosses the aiming point on it's way up at about 25 yards, then rises to about 2" above the aiming point at 50 - 60 yards then drops back down to the arrive at the aiming point at 100 yards. It might not be that much drop though, I'm not sure on a shotgun ballistics.

Hence, the common suggestion here of taking dead aim and pulling the trigger. You'll never be off more than 2" high or low and at 20 yards you should be almost exactly on your aiming point.

use the pathagorean equation and it will give you exact footage
2's mean squred
a2+b2=c2

as close as that is...you should b dead on

As people said above, you should be pretty much dead on. Here is a link for one of Winchesters Sabots that has a decent chart for you.

Personally, I'd "Bite the Bullet" and set up and take at least one shot through at at 20 yards or so. Im sure it will be dead on but im you sure would rather waste a few bucks on a shot than spend an extra few hours blood trailing a deer.
