[QUOTE="Bart B, post: 1796970, member: 5302"] The formula for horizontal impact shift from cant is: Bullet drop at target range X sine of the cant angle: Example for 308 Win at 1000 yards with a 1 degree cant: 400" X .01745 = 6.98" The line of fire moved that far to the right 400 inches above the point of aim. Yes, there's a tiny bit of vertical drop. It's the difference between 400" and 400 X cosine of 1 degree. About .061 inch [/QUOTE]
