VarmintGuy: 2 Chucks is not a large enough comparison pool to write off this fine bullet just yet.

I agree with you there! I did shoot a sagerat at 100yds this weekend and the 70BT still did not give the terminal performance of my 22-250 with 55BTs. Maybe I'm just excepting too much, but I figured if the 22-250 with 55BTs @3650-3700fps is good, then the 243 with 70BTs @ 3600 had got to be as good if not much better. I have 60 some rounds of the 70BTs loaded up and will shoot them this season. I just don't want to waste an accurate MarkX rifle if it doesn't suit my needs.
