Quick question for you smart folks :)
 

I have a slug gun that is sighted in @ 100 yards.

I now have a tree stand that is 14 ft up and 20 yards from where the deer pass.
Instead of wasting time and MONEY re-sighting my gun....what can I expect if I want to shoot my slug gun from this stand?
Mossy 535 ATS with rifled barrel and a scope.

Aim dead on, high, or low?

Thanks a ton!!

Don

not to be a smartass but why not shoot a couple rounds at a target 20 yards and figure out exactly where you should be aiming. its gonna be hard to tell you exactly where to aim.

Have you PRICED sabot slugs?! ..... That is why!!!!


I figured I would start with the FREE research and work my way up!
If someone had previous experience with this and knew the drop/rise differential then I could save $10 bucks or so on slugs.

With that short distance, I don't think you aim any different than if you were on level ground. The angle won't come into play. You only need to figure where your impact point is at, at the 20 yard mark. You should know with just one good shot at the range or wherever.

Set up a target at 20 yards, make one good shot... and there you go!

That's the best I got. You could advise a chart somewhere, but it's always best to back it up with some real-world shots and you could verify it with one good shot.(notice emphasis on "one shot" 3 times. LOL!)

Good luck,

Dead on...

Where does your gun hit at 100? If you are zeroed for 100, aim dead on at any distance from 0 to 100.

Even if you were a couple inches high at 100, you could aim dead on at 20. You might be say 2-3 inches high at 50 or 75 though. Nothing to worry about if you shoot for the middle of the deer, top to bottom.

I would like to think if you know the velocity & BC of the round your using, plug that information into a ballistic program and you will have your answer. At the very least you'll be close enough. Ballistically I think you should be able to hold dead on and still be within a 8" vital at 20 yards especially if your shooting a premium round. I like the Hornady 2 3/4 SST sabot, they have been fairly accurate out of my Moosberg. 100 yards is generally max distance for any rifled shotgun and I have mine sighted in to shoot 1" low at that distance and been able to hold dead on at any distance right out threw 100 yards. But thats my combination and not yours so your results may not be the same. If it were me I would do like isnipe suggested and break down a buy a box to find out for sure. I certainly wouldn't get the green light from anyone and go hunting without being absolutly possitive how my shotgun shoots. That would be the ethical way to approach this, I don't know maybe it's just me!

dead on, so close that it doesnt matter...

I am not so sure about dead on. I had the same situation except that the deer was about 15 feet. The slug went over its back. It stood there, I aimed low and killed it. At 20 yards you may be able to hold dead on, but who really knows.

Sorry folks, but no one on here can tell you how your set up is going to perform. They can only provide "educated" guesses. I suggest test it yourself.

I agree 100%. Many bullet trajectories are at zero at 25 yds, high at 50 and back to zero at 100 yds. A slug should follow that plain except with a bigger curve. Other than a shot at 5 yards the impact point has to be within a couple of inches no matter what yardage inside 100...even with a slug.

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.

Distance in Tree Stand to Target
 

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.

if you are using a scope I assume and you are higher than the target, and you stand up and point the gun down, you will change the hold anfle of the gun. that might explain the miss. make sure you keep your eye/cheek/ line of sight or the paralax in the scope will give you a false sight picture.

WOW!
Lot's of things to thing about!
I'll let you all know how it goes.

No, not really. The only thing you need to think about is placing the cross hairs on the chest and pulling the trigger. From 0-100 yards you aren't going to be more than about an inch and a half higher than your point of aim.

It's that simple, don't make it more complicated than it has to be.

I have a 870 express, rifled barrel, 2x scope sighted in at 60 yds. (all my slug hunting is in pretty thick swampy stuff)I aim dead on from 16' high stands at about 20 to 30 yds. and have taken several deer w/no problems. Just my 2 cents worth, hope it helps. BTW, I use 2 3/4" Barnes expanders.

ditto dead on if its zeroed

BINGOOOOO..

hold dead on

WOO HOO...
Just went out to my stand....
There was a knot on a tree about 4 feet up, and right beside where I will expect the deer to show.
I fired one lightfield hybrid elite, and plowed a HUGE hole dead center of the knot!!!

Thanks again guys... I'll keep you posted, but today it's BOW season! :)

DIY camo on the slug barrel and scope.

So it was dead on?? Thanks for the info..because I'm using slugs as well

.I do know my bow was not dead on It was a t 20 yds but at 10 yds I had to aim low to hit the heart area..and this was consistent..At 10 yds I had to aim at the bottom of the animal to consistency hit the heart..at 20 yds It was perfect..this was with my bow..

I say "dead on" but it may have been ONE inch low (could have been user error as well).... I assume it would climb a bit from there to be a few inches high at 50 yards, then back down to dead on at 100.
Either way.... I think I got the DEAD part right :)

One inch won't make any difference. Shooting at a target above or below a level plane does effect the strike of the round because of the difference in the angle of the bore relative to the line of sight. Any angle will cause the bullet to hit HIGH. The best way to visualize this is to imagine shooting at a target directly below you. The bullet it converging with the line of sight when fired, but the line of sight is parallel to the force of gravity, so the bullet crosses the line of sight but doesn't have gravity to pull it back down toward the line of sight as it does when fired horizontally. As a result the bullet will, after crossing the line of sight, continue to diverge. As the angle moves closer to horizontal, the effect becomes less and less. The same applies to shots taking uphill. This is a factor long range shooters have to factor into their scope adjustments, but at short ranges, it's not really a factor. It is a problem for bowhunters because of the relatively slow projectile and much greater difference between the line of sight and the launch angle of the arrow.

At 20 yards with a gun, the difference is negligible, as you've witnessed from your experiment. If you were shooting down a mountainside with a 30* incline at a target 400 yards away, it'd be a real problem that you'd have to adjust for.
