Honestly, with a 4x scope, I don't think much about the color. I'm just aiming small. Im about to rectify this situation tomorrow when I top off my newly arrived White Oak Armament upper with a 16x Sightron. Much fun and new development to be had. I wish I could rename this thread. ETA: Nevermind, I figured it out.
You can rename the thread. Look for "thread tools" in the upper right corner next to watch/unwatch thread. Wow... that 16x will be a whole other animal. I have a DD MK12 with a Leupold VX3 1.5-5 x 20mm on it and a few hundred hand loads from last winter that I need to work through. Mostly with the 65gr Sierra GameKing (#1395) but also some heavier stuff.
Got it on paper, then sighted in and was left with my last three rounds of Hornady Black. I'm getting somewhere now.
Doesn't come with instructions and the help page ain't worth much. Just play with it and it will become more intuitive that you expect. I struggled a little. But, I'm an oaf.
I received the new 73gr Hornady ELD Match bullets yesterday. Very promising results. Very nice 10 rd group.
