Niner, they were 165gr Hornady Interbonds. Hornady had a specialized way of loading the powder via some type of rotating filler system, and some special blend that they never made fully public. They dropped the ammunition and have switched over to Superformance Ammunition which you can buy Superformance powder for. I haven't seen Interbond bullets for a while either and I don't know if they are still making them.
