How can such a little product make so much sense?

Sized like a credit card. Small enough to fit in your pocket. Long distance shooting demands accuracy that a 100 yards poke at a deer don't demand.

When I was growing up I was told, "Hold high for downhill shots and low for uphill shots. " Clearly the mentor of my youth never did any long distance shooting of consequence. How low or high? It wasn't until I got to school that I figured out that you hold low shooting in either direction, up or down.

Great, one piece of the puzzle was acquired but still an important component was missing. What distance do I hold for at various angles? Enter the Slope Doper.

Simply place on your barrel as if you were going to shoot. That will give you the angle and the corresponding quotient. Using your laser range finder simply multiply the distance by the quotient.

575 yards to target X 0.87 quotient (30 degree slope) = 575 × 0.87 = 500.

So you would hold, or dial up your turrets, for 500 yards.

If you're like me you left math when you left high school. I'm no math whiz. I need all the help I can get. The Slope Doper is small, lightweight, and most of all ready to use. I do recommend one carry a small calculator to do the calculations, most phones now have this feature, but if you desire you can do it by pen and paper.

This little gadget comes with instructions that are easy to follow and takes the guesswork out of those difficult shots. I elect to use this over the ballistic drop feature in my laser rangefinder because the exact bullet drop of my loads is not in the pre set program. Since error is magnified at distance, in my case, I elected to use a different way to solve my problem.

The Slope Doper cost less than a box of premium bullets and helps to take the guess work out of those difficult angled shots. I highly recommend it.

Yes, I've heard good things about this, as well as the (much more expensive) devices that clamp onto the scope and provide the info.

Our hunting world is not flat. I'm convinced most riflemen don't really understand what happens out there, at longish ranges, with steep slopes.

How does this thing deal with various barrel tapers/contours?

That could throw the angle off couldn't it?

I hadn't considered that Guy.
I doubt it would be enough to matter at all but the most extreme ranges. I at least haven't had it be an issue but I'm not going real far. [emoji4]

I think you're right.
Makes me wish I'd paid more attention in geometry class.
 
I use Theodolite on my iphone (free app), enter the angle in my ballistics program, and I'm good to go. Free is good. Try it once.

Addendum - apparently Theodolite free is no longer free, but $3.99.
Still works great.

This will do same thing and more? Plus it does not need a cell phone signal to work!
Most people are running Cosine Indicators with levels on them and they are stupid expensive but makes incline and decline measurements pretty fast!

I say they are not cheap but it depends which 1 ya buy and I guess the 1 I have been looking at it too much :lol:
 
Theodolite doesn't need a cell phone signal. It will even work on an ipod touch.
 
I'll stick with the slope doper because it works for me and it didn't cost me a lot.

Why couldn't you measure off the receiver instead of the barrel? That would eliminate the barrel taper from the equation.
 
I measure off the edge of my stock.
It's flat, and no contour.
 
There ya go. Receiver or stock should work.

First post said "place on barrel" and my first thought was "barrels are tapered" there went your angle measurement.

Yeah, haste in posting.
Is that a miswriter crime? [emoji4]
