Very good words Mark! I had an 'object lesson' on this topic while hunting in Wyoming for Pronghorn. My home range max distance is 547 yards and there's very little elevation change and usually not much wind. I was faced with a 330 yard full value Wyoming gusting wind at what felt like a massive downhill angle. I have exactly zero experience in that condition and no way to practice such a shot. I was on the ridgeline shooting down into the valley. I connected, but poorly. Second shot sailed just over it's back. Now get this: The pro guide said, 'Shoot a foot in front of him.' I did and put the next one right behind the shoulder. That was a LOT of wind drift and elevation change for me to deal with. AND....in my honest ignorance, I didn't confirm zero in WY before the hunt because I had absolutely dialed that .308 in with my handloads of 150 gr SST's. Later, when I did zero in WY, it was shooting high and right. (Original zero was in Pennsylvania at 800 ft ASL) Wyoming was 5K feet ASL. When I got home, it was shooting low and left. I mentioned that to an engineer that works for Kestrel and he was almost giddy and told me he'd never actually talked to anyone that had that experience though he knew the physics behind it. Lesson learned for me! Always confirm zero! Thanks for another great video!
🗣The Hornady 150gr SST is a good round. I load it in my .243, .270, .308, and .30/06 (that is I load the SST in all four calibers) And YES, always confirm ZERO.
Excellent as always. This is an important topic if only to correct a common misconception that many hunters and other shooters suffer from. Often someone will be told, “You’re shooting up at an angle, so aim low,” but there’s usually no guidance on how “low.” In fact, and as mentioned, at short ranges and moderate angles the corrections are very minor. As also mentioned, a good ballistics solver app is the best way to determine the effect that shooting at an angle has on the elevation (and windage) correction necessary. Another advantage of a good app is that it permits us to experiment to see what effects there will be in different theoretical situations.
Very informative,. One day I will have time to spend time shooting like I want to. Until then keep the videos coming please. Have a great day and once hey from the states
For normal hunting distances, say 400-500 yards max, if angle is steep hold a half moa low, if it's moderate or slight, quarter moa. Hold low on the vital/kill zone. Don't hold off meat. This has worked well for me over the years. fwiw.
Phew, i was worried you were going to say the 'horizontal distance' theory (that i was tought) was an old wives tale 😅. Never thought about the difference in barometric pressure over large altitude change though. It changes again when you shoot near on vertical as gravity is then acting more or less parallel to bullet travel so shot wont come back through the sight line again, it just keeps going up in the scope (only really happens when shooting a pest up the top of a really tall tree with the likes of a .22LR or air rifle)
On ya Mark I normally follow and totally understand your tutorials but this one was a bit hard for me to get in my thick head now I gota find a book and do more learning 🤓🤔
You are not alone. I did not follow him either. He spent considerable time explaining a simple concept: Bullet drop, due to the gravity, depends on the time it takes to reach the target. The gravity effect on a bullet is constant regardless of what angle, or speed it travels. Only the time it takes to get to the target matters. Regardless, I still have not idea what he was trying to say.
I've lost track of the number of times I've tried to explain that slope distance has the same effect, whether it's an uphill or downhill slope. You'll get these people, who'll insist that you'll shoot high while shooting down and low when shooting up. And they let these people vote and drive lol.
I don’t think it’s silly shooting a .303 at 3000. I think it’s pretty cool. I have a .270 Winchester and I would love to see y’all try 3000 yards with one.
I was really embarrassed when I realised this. The most effect range has on bullet drop occurs when the shot is horizontal: vertically up or down has no effect at all. Obvious, only took me about 50 years to realise! In addition, and sort of counter-terrorism intuitively, shooting vertically up wouldn't affect maximum range much, since gravity only subtracts 32 feet per second per second from the velocity. Come to think about it range might actually increase, due to the drop in air density with rising altitude. I'm sure the answer to this is well known, just not by me!
Geoff Keeler, And tho not counter -intuitively, shooting vertically down would add ( or more aptly, lessen the decrease over a longer time ) by your 32 fps / ps formula ( at least till terminal velocity is reached / impact ). . . .

Thank you Mark. For everything.
Long time viewer, and I still can't believe how much knowledge and insight you have.
Have an amazing day Mark!
Thank you Man, glad you liked, Cheers and all the best.

Thanks John, Cheers
Thanks Mark. You have done it again. Great explanation with simple solution. Much appreciated.
Cheers
Great lesson. Made a lot of sense!
This one helped me a bunch.
Thanks. Great video.
Mark, USA🇺🇸
Cheers Man, thanks
Great video Mark! I always enjoy hearing your technical talks and sometimes I even mange to learn something! Lol Cheers to Sam!
Lol, thanks Rev, Cheers and all the best
Excellent explanation Mark. Thank you🙏
cheers Waldo, thanks

Great video guys, clear and easy to follow
Cheers Mike

Keen to see more ELR vids of you shooting up hill, but I can understand why the trace would be safer shooting down on the properties you shoot on.
We have those videos, all on the channel, Cheers
Awesome.!!

Sort of done that, video on the channel, Cheers
@@markandsamafterwork oh, I guessed that I missed it. I’ll find it and watch it. I appreciate what y’all do.
If your shooting up/down 3000ft I gotta hope something has gone horribly wrong. 😂
Lol, yup, cheers

It's a simple thing says the man who lobs .303s 3000 yards...........
Lol, Cheers
