# Since this has been a day of gun debates, why not have firearm lesson #2?

If you are shooting uphill or downhill with a rifle, what is it commonly necessary to do to hit your target?
Good answer but not the one I'm looking for lol.
Where's my fellow gun nuts?

• The only thing I can think of is that the drop will be *slightly* different. The drop is constant in a vertical direction. On level ground the drop is perpendicular to the ground. On a hill, it is not perpendicular, so the drop in relation to the ground will be different than on a horizontal surface.

• Correct. When shooting up or downhill, it's necessary to aim lower at any given distance than shooting a flat, horizontal plane. The steeper the angle, the lower you have to aim. The formula is... yds x (cosine x degrees) = horizontal distance to target.

So, say target is 650 yards and it's a 30 degree angle. Cosine of 30 degrees is.866. So,
650 x.866 = 562.9
So you would adjust the elevation on the scope to 560 yds (rounded is close enough). Which on my 308 would be 12.6 minutes of elevation and adjust for windage if necessary and, bingo a hit. So you're setting the scope for only 560 yards even thought the target distance for line of sight is 650 yds. so you're aiming lower. Understand?

• LOL. I'll just stick with black powder at a hundred yards. As long as I hit paper I'm satisfied. :)

• Lol, I shoot those too. Actually, my current project is my flintlock. I've been grinding down the front sight to change the point of impact and I'm almost there maybe another.010-.015" and I'll have it done. It's been six weeks since I started it but enjoyable and relaxing.
