I've got a Burris FFII w/ ballistic plex recticle on my BAR 30-06 and like it very much.

You mentioned occasionally shooting to 350-400yds. The Ballistic Plex recticle has hash marks for 200, 300, 400 & 500 Yds. You sight it at 100 yds and then use the appropriate hash mark when needed. Totally eliminates guesswork as to the amount of hold-over at various yardages.

I haven't got to test my gun at 300 & over, but sighted in at 100Yds, she is dead on at 200Yds using the first hashmark.
