.284 Caliber Bullets Custom Built for Accuracy | Matrix Ballistics I can't find any information on them. I'm thinking about working up a load for my 7 Rem Mag with these, Retumbo, CCI BR2s, and Win brass, but I'd like to see how these stack up against the 180 Berger Hybrids. The only BC numbers Matrix offers is the static BC of .8071... If someone has some real actual BC numbers for this bullet I'd like to run the numbers and compare to see what would be best from my rifle. Thanks for looking. Tim.
