I am in Timbercruiser's camp on the German #4. I tried one of the "multi-mark" scopes on a ML and found it too busy for me to accomplish quick target acquisition. I am confident that with practice, that could have been at least mitigated, if not totally overcome. I do not do much truly long range hunting or range shooting for that matter. About 200 yards is it where i hunt 99.5% of the time, with well over 75% of my shots 100 +/- yards. Holding dead on with my rifle zeroed 1" high at 100 yards works excellent for me.
I have been out west a few times, taking mule deer out to about 350 - 375. I did a bunch of range work, zeroed at 200 yards. I made me a "key" from that practice to help me with"hold-over". Laminated it and taped it to the rifle stock. I practiced out to 500 yards but decided that 400 yards would be my limit. The German #4 made it relatively easy for me to work this out. Plus for my old eyes, the heavy plex works great in low light.
