I've not gotten hands on the newer version yet, but I use a 3-12x42 P3L with the 3.2 mil BDC. As I understand it, the newer version is the same but has 4.8 mil on the dial.

With any decent BC bullet/round, the 3.2 is fine for my hunting. The 4.8 would allow me to play a bit further though, so I'm hoping they will retrofit/upgrade at some point.
