If you're shooting at a steep uphill or downhill target at long distance and you don’t compensate for the difference in gravity, you’ll miss. Rifle expert Jeff Johnston shows how to make that shot! Posted on 09/22/2017 8:33:22 AM PDT by w1n1
If you're shooting at a steep uphill or downhill target at long distance and you don’t compensate for the difference in gravity, you’ll miss. Rifle expert Jeff Johnston shows how to make that shot!
Some hunters know that when facing a long downhill shot angle they are getting slightly lower than normal. That’s because gravity pull is greatest on objects that is parallel to earth. And so what this means is that a bullet fired at an angle won’t drop as much as one fired over level ground. But surprisingly this also means that a bullet will strike fire when shooting up hills as well.
Of course how much higher a bullet will hit is a product than the distinctness of the hill and the range to the target. For example 300 yards shot at a 45 degree angle which is pretty darn steep with this .306 right here with strike constantly six inches high. So generally hunters taking shots at... Read and see the rest of this video on long range - extreme angle shot here.
Shooting 101.
Whoever wrote this didn't pass freshman physics. You may assume that g is a constant for all intents and purposes over the trajectory of any ballistic projectile shot at the earth's surface and travelling several thousand yards or less before impact.
Yeah no kidding. Sure the ballistic arc looks different at an angle but that is not due to gravity changing.
I expect this level of proofreading from liberals, not from normal people. My revisions below are a little better:
Some hunters know that when facing a long downhill shot angle they are getting hitting slightly lower than normal. That’s because gravity [gravity's] pull is greatest on objects that is are [grammar fixed, but the science and math are incorrect and confusing] parallel to earth. And so what this means is that a bullet fired at an angle won’t drop as much as one fired over level ground. But surprisingly this also means that a bullet will strike fire higher [?] when shooting up hills as well. Of course how much higher a bullet will hit is a product than the distinctness [I don't know how to fix this one] of the hill and the range to the target.
I try not to be the grammar Nazi on discussion posts here, but articles should have higher standards. While covering an important point, the writing on this one was a bit much for me. The errors both distract from the main point and reduce clarity.
I saw that, too. I sure wouldn’t want Mr. Johnson tutoring my kid in physics. What a dumb thing to say.
Following his logic, gravity has a larger affect on me when walking horizontally than when jumping vertically. Gravity “knows” which way you are moving.
“Product of ‘distinctness’ and range”
LOL...pardon me, gotta go buy a new “Distinctness Meter.”
A bullet’s velocity can be divided into horizontal and vertical compoents. An initial horizontal shot has a zero vertical component except for gravity which caused the bullet to drop.
A sharply elevated shot has a strong vertical component that is greater than the effect of gravity, at least until air resistance reduced the vertical velocity so that gravity become dominant at the apogee (or the bullet hits the target).

It appears that this article was created with a speech-to-text app. This sort of technology is not always friendly, especially if a “writer” totally blows off the proofreading work.
Can you fix that one? I was lost on “distinctness and range”; I don’t know what he was trying to say.
That makes sense. Thank you.

Agreed. The writer should stay away from physics, unless they want to use vectors correctly.
He should have used a diagram or two. Here's a very simple one (but it ignores the optical line through the scope or sights):
“But surprisingly this also means that a bullet will strike fire when shooting up hills as well. Of course how much higher a bullet will hit is a product than the distinctness of the hill and the range to the target.” Was this article dictated? Did “Tootsie” the steno fumble the words “fire” and “higher”? Or, in what way does a bullet aimed puphill strike FIRE? That term is strange to me.
Agreed. A down slope shot travels a modicum faster than a level shot because of the effect of gra\vity. Thus requiring less elevation compensation. I think it's called...angular momentum. Unless, of course, I'm wrong.

My Ballistic app on my iPhone makes the correction for shooting uphill or down hill. I have a bracket on my gun to mount the iphone and it automatically measures the angle and puts into the calculation. Also the app automatically gets info on temperature and pressure from the nearest weather stationed the internet as well a altitude from gps for the calculation.
Have made several long range hunting shots with this app, longest was 970 yards on antelope in Wyoming.
Heck upn` here in the mountains usn`s were trained as kids for automatic compensation of a groundhog`s shadow being off kilter a slight bit for the downhill shot -
Who are these morons who never fired a .22 when they are 6 years old, then have the gall write about guns??
Interesting. Show this to our range rep.
