Len, i'm sorry but i have to disagree with your answer as to why the bullets impact higher when shooting on an angle. gravity has nothing to do with it. the reason the bullets impact higher is because of the vertical difference of the centerline of the barrel and the line of sight when they're at an angle as compared to horizontal.

Hi Lefty,

on base of your bullet info, I just generate a drop table from 0 - 1500yards.
So - first column = distance of shooting
from the 2nd to the last column is how you will aim at that distance.

examples:
so you are hunting on hill side of the mounting and you spot an animal.
Ranging the distance with a rangefinder and you read - 400yards
if you are shooting strait (no uphill or downhill) - you will aim as you are shooting for 400yrds.
if between you and the animal is 5 degree slope = you will aim as you are shoting at 396yrds
if between you and the animal is 10 degree slope = you will aim as you are shoting at 392yrds
if between you and the animal is 15 degree slope = you will aim as you are shoting at 384yrds
if between you and the animal is 20 degree slope = you will aim as you are shoting at 376yrds
if between you and the animal is 25 degree slope = you will aim as you are shoting at 360yrds
and so on...
JUST SEE THE TABLE.

400 400 396 392 384 376 360 348 328 308 280 256

as you see from zero to 20 degree slope is almost no need to use corection of shooting at big game.
but passing 20 degree slope you have to do aiming corection, if not you will miss shooting high on top of the target. With how match? Just see the tabel.

I hope this helps.
chris

Thanks very much Chris, this will be a great help. So this drop table will work for either uphill or down hill shooting?

Yes, for both you have to aim the same.
