You made some great points Jerry, and I think the winds we saw at Connaught this weekend bear out many of your conclusions. What I took away from this weekend was that the heavy 308 bullet I shoot is more forgiving in tricky conditions whereas the 223s have the potential to be more accurate in calm, or even steady conditions.
For those who are interested (and I post this only because it was part of the bet, and I told Manitou I would) a few of us were "socializing" after dinner last night, discussing the merits of our respective calibers and decided we should settle things once and for all by running a side team match on Sunday, with the 308s vs. the 223s for the Sunday aggregate.
I'm happy to report that the heavy 308s carried the day, with one team coming out a full 50 pts ahead of "Team Mouse Gun". Sorry Paul
