[QUOTE="woods, post: 252397, member: 6042"] Hey mike Taking a typical 45-70 shooting a 300 gr bullet at a typical 2200 fps with a typical ballistic coefficient of .200 would have the following trajectory when zeroed at 100 yards: 100 yds - 0" 150 yds - 3" 200 yds - 9" 250 yds - 19" 300 yds - 33.6" So the reticle will subtend the following at the following yardages when zeroed at 100 yards: crosshairs - 100 yds - 0" 1st line down - 150 yds - 2.25" (1.5x1.5=2.25") 2nd line down - 200 yds - 9" (4.5x2=9") 3rd line down - 250 yds - 19" (7.6x2.5=19" 4th line down - 300 yds - 33" (11x3=33") Dude, just zero at 100 yards and the reticle will match that trajectory exactly for every 50 yards out to 300 yards. They were made for each other! What's the problem? [/QUOTE]
