Ballistic Coefficient vs. Accuracy?

[Don McDowell]

Late to the party, but if given the choice, I would first test the bullet on the right, and then see how the bullet on the left compared.
Personally I don't think the "transonic" zone is as much trouble as some would make it out to be. I'm fairly well convinced most of the problems occur in long range matches due to wind currents above the flags where the bullet is traveling and beginning the apex when shooting at distance. We simply can't see what's going on above the flags, except at Raton it is sometimes helpful when spotting to look at the mirage against the mountain in the back ground well above the target butts.
It was interesting in the pits at Phoenix this year, even at 1000 yards when the winds were full value tail winds the muzzle report and the bullet would arrive at the same time. Wind switch a bit to one side or the other and the bullet got there first.
Also note that pulling targets for someone shooting a 2 7/8 target at 200 and 300 yards ear plugs are still a handy thing to have.
