[QUOTE="WiscGunner, post: 1981231, member: 97288"] Are correct that the shot angle is important if enough distance is involved. However you are very wrong in saying the linear distance reduction of 2yrds is equal to vertical drop. This would mean the bullet if falling at a 45* angle to target. So, you are terribly far off with respect to a 7rem mag at 500yrds but might be closer with a 45scp at 500yrds. Yes the angle should be included if necessary. The accurate method is to enter the LOS range AND angle into the ballistic calculator so the calculator factors the full distance of environmentals on the bullet. However, 500 yrds is not a long distance for a centerfire rifle and 2* is not a concerning angle. Certainly not for hunting and likely not even adjustable at such a short range with standard scope turrets. With the OP data entered into BallisticsARC there is a .1MOA difference between 495 and 500yrds at a 0* shot angle. The same difference exists with a 2* shot angle (34.3” of drop at 495yrds and 35.3” of drop at 500yrds). A 10degree angle is .2moa so you could fudge it and take a click off for a 10* angled shot.
