Currently have Ares BTR 4.5-27 I can get 20.3 dialed tracking accurately and 10 off the etched reticle so 30.3 mils max potential, but have to back off the mag a ton so not ideal. I like the glass and the reticle thickness is my fav of all the glass I have looked through, but clearly I'm lacking with a 10m etched hold over limit....if I had 20 I wouldn't be looking around. I am not the guy who keeps up on every new offering of scope to hit the market and have been quite content with this Athlon until recently due to the aforementioned limitations.....getting out this long was not possible. I'm certain there are piles of folks who have been in this position and suddenly could shoot a long way and then found out....time for an equipment change. Would love to hear what direction you went....thanks
