Long range shooting question
On 220 yard shot with a 10 degree uphill angle how much does it decrease the yardage?

5-10 degree slope = 98% of slope distance
15-20 degree slope = 95% of slope distance
25-30 degree slope = 90% of slope distance
35-40 degree slope = 80% of slope distance
45 degree slope = 70% of slope distance
For more exact numbers you need to get out a COSINE CHART.0 -

Check about the 1:50 mark of the vid!

What game are you hunting at that distance? Wood Chuck's or gophers and other small varmits? Or things that can be hard to sneak up on like elk?
Regardless, good luck on good shot placement! And nice to see you trying to ensure as accurate and ethical shot placement as possible.

Going by the example you gave, unless you are talking rimfire the difference is insignificant. We are talking less than 15 FEET of difference. In other words don't worry about it. Bob 0 -
Shooting a 45-70 with 405 gr cast lead bullet in the high country. 0 -
You didn't give velocity but with a hundred yard zero a 405gr @ 1350fps drops about 24 inches at 200 yards. At 220 about 30 inches. At 10 degree angle I am guessing 29 inch drop. So like I said don't worry to much just shoot the critter. Practice a bit at 220 on the flat and when you shoot at 10 degrees the group will be about an inch higher. I don't think a deer will notice.

Will probably something larger than a deer, but thanks for the info. 0
