Thread: uphill and downhill shooting

ok weve probably coverd this before but i cant get my head around the poi change when shooting down hill i think for some reason the shot tends to go high why is that

Uphill and downhill is the same shot goes high.

It travels less horizontal distance across gravity so the drop is equal to the horisontal distance. (extremely simplified)

Because you are not covering the true horizontal component of the curve. Trigonometry sucks but it is where your answer lies😆

Magic.

Incline shooting still messes me up more than any other environmental factors..

Rabbits at 1-200m, 25º or more incline.. trips me up like nothing else, even though 'in theory' I should have everything worked out for it.

we were shooting at some goats 217m away measured with a rangefinder steep down hill and we were having troubles hitting them made it harder as couldnt see where the shots were going then remembered they tend to go high

Perfect!

Remember also when shooting at living things the path of your bullet threw the animal.
Animals stand upright no mater the slope they are on so if you are shooting steeply up or downhill at an animal standing broadside to you and the slope for instance your normal aim point on the animal(assuming you have the drops etc compleatly sorted already) say half chest depth for lung shot will enter at that point but angle up or down depending on shot threw the animal effectively making your shot higher than normal if the animal was above you and lower if below you.
This effect is really peanuts compared to the ballistic effects of angle and range but certainly worth consideration say shooting goats from bluffs either above or below and shorter ranges.
It is the shorter ranges where you will get the most angular change and it is important to change aim point accordingly.

@Taff

And this is why I like my Leupold laser rangefinder. It calculates the True ballistic range. e.g. 400yd actual distance to target at 40 degree incline. rangefinder shows TBR of 335yd. Dial for 335 yd and bang on target.

Have to agree I got it all wrong yesterday, left my range finder home as we were expecting to find goats in the bush, set scope for what should have been 200 mtrs , but as it was practically a 60 deg angle up hill, missed 3 times yes 3times, wound it back to 100 and dropped two, even worse was the fact I though I had lost my I phone somewhere on the top of the hill ( only 350m high ) through thick bush, realising I had turned data off, I could not use " find my phone" and also put it on silent, I went and bought another phone, only to find it tucked in between the seat of the ute, yep a good day all around.

That is something I had never taken into account, but I should have on my last trip down queenstown way as it had some extreme angles

Not from where I was standing. You worked out what was wrong in seconds, made scope adjustments, then pulled off two very difficult shots.

That is slightly less impressive
