[QUOTE="Jeff In TX, post: 17441, member: 1522"] OK here’s the scenario. Urban tactical situation. Roof top tactical shooter, bad guy is laser ranged at 120 yards. Angle of the shot is 60 degrees. Shooting a 168 sierra BTHP at 2600” per second. You get one shot to drop the bad guy. Officer in-charge at the seen gives you the green light. Lives are on the line and you only get one shot. Do you use the cosine angle, which makes it a 60-yard shot, or do you use a calculated ballistic drop for 120 yards? Sorry folks, no spotter shot for this one. [/QUOTE]
