[QUOTE="sscoyote, post: 2064743, member: 1133"] Love manipulating subtention apps. with reticles, iron sights and even archery sight pins. Awhile back a buddy got an old Parker Hale 243 that used to be quite the shooter. He had a Nikon 3200 3-9X Nikoplex reticle on it. We weren't far from a prairie dog town so we thought to test it at long-range to see if there was any accuracy left in it. So I measured the plex post tip at 100 yds. on a cactus @9x, ran the ballistics then using maybe 3100 with an 80 gr. bullet (been awhile now). Can't remember what the MOA was at 500 yds. but knowing that reticle subtention is inversely proportional to magnification, I calcd. the magnification that would give us the required MOA we needed for the lower plex post tip to match the calculated 500-yd. zero, and it was something like 3.7X. So we cranked the scope to that power and my buddy gets set up on the edge of a prairie dog town. I lasered one on the bottom of a tepee butte right at 500. My buddy nailed the dog on the 2nd shot after allowing for a bit more windage than the 1st shot. He yelled out, "alright sniper"! I just chuckled. Nothing quite like subtention fun. [/QUOTE]
