Thanks for the info Al. Did you end up with a longer COL than A factory Hornady 250 round ?
I did a lot of searching and found this article http://www.namlhunt.com/mltrajectory.html
it is about the Ballistic Supremes and not the Match Hunters it brings a little doubt into the equation, I could not find part 2 of this article that they mentioned so I assume it was never published.
although the BC that this article gives the Parker Productions are generally higher than other bullets of the same weight, I am not sure the price difference would make up for the down range improvement. I guess there is only one way to find out, and that is load some and shoot at long range and see how they perform.
