Not really a kill, but i did have a fun shot using a buddies rifle by applying math on a blade of grass at 250 or so awhile back. This buddy had a 6.5-20x Leupold/Duplex reticle on his rig for lack of another scope. We were trying to get to the longest possible range with it and i developed a system for him using the plex post tips at 6.5 power where the subtension between x-hair and lower PPT becomes 4 MOA. Sighted in for 175 yds. 250 yds. is .9 of the way down to the PPT. After an unsuccessful coyote stand one day last season we though to take a shot at a wide grass blade stickin' out of the snow at 250. I wasn't sure what the hold was so my buddy says .8 down. So i hold for it and sure enuf miss just low. I then looked in the Butler Creek scope cap cover and saw it's supposed to be .9, and on that next shot hit the grass blade and it broke off. Thought that was a heckuva' fun shot...at least my kind of a rewarding long-ranger.
We have shot out to 400-450 on rocks and such with it using the tgt. turret.
