ok, thanks jpk, will try that too!! looking forward to it when the snow's gone and the weather's a bit better.
i tried to put an xl sheet attached, but it didn't work.
anyway, i ran the numbers and for the .270 and .300 wm the 200 zero makes most sense as it alone gives protection to the over 200 shot for elk and antelope, with apogees of both between 1.3 and 1.5 at 100 and 150 yds. but with the .223 69 gr hp it's a tossup and depends.
see below: the flatter trajectory of the 100-200 yd zeros make more sense inside 200 yds, but the 50 yd zero gives me the same apogee as i'm used to, up 1.5-1.8 at 100 and 150 that i'm used to with my longer range zeroes! so i think now that i'll just stay with the 50 yd zero that acts in that range that i'm used to w/o thinking, and gives a better dayscope range beyond 200 as well if i need it. if this ar was my first rifle and for this job inside 200 yds i'd go with the 100-200 options. either way you look at it, you're in the kill zone without thinking much about it. i was shooting at targets in total darkness last night and watching animals. lit up like xmas trees. so exciting/amazing.
