Black Hills 87 Gr Barnes 556?

[markm]

Impressive trajectory with same come ups as your 77 gr load at assumed lower velocity.
Any idea what BC is?

No idea. The odd thing is the ammo is assembled with 07 LC brass. The lot number COULD indicate 09 production?

Ammo showed mild swipes in our buddy's KAC SR whatever gun, but didn't show any pressure signs in the Bolt gun. (different chamber/barrel)

The ammo shot just under our pet 77-grain load in fps. So 10 grains higher and near matched our 77's, BH doing some voodoo velocity shit that's impressive.
