Hello All,
Well I finally heard back from Black Hills about the ammo problem.Here is what they said " We've finally come to a conclusion that it appears to be the brass that we began using last year that is causing the troubles you reported. Apparently the brass is a bit softer than the Norma and the Lapua made brass we've used in the past. This softer brass combined with the pressure curve of the powder we use seems to cause pressure signs and sticking in some weapons. We fired rteturned rounds from you and another person in serveral weapons here at the shop. functioning would be flawless in one and then we'd see hard bolt lift and stickiness in the next. Firing the rounds in a pressure test barrel showed them to be within specs for similar calibers such as the 270Win and 25-06 Remington. Since the 6.5x284 Norma has never been accepted into the Sporting Arms and Ammunition Manufactorers Institute (SAAMI) manual there's no established pressure standards for this round. Ammunition manufactures such as ourselves use similar cartridges as examples to go by."
They sent me a refund check for the ammo and they are sending me Lapua brass for free. Black Hills is a STAND UP COMPANY!!!!
Hope this helps other's in the future.

P.S. If anyone has a pet load they'd like to share with me, please let me know.
