I have a Christian arms 300 PRC carbon fiber barrel 1-8 twist. I'm getting ready to work out a load for it. I already have h1000 powder Fed 215 magnum primers and berger 210 gen vld bullets. I was wondering if anyone has worked out a load with this yet. And I have Hornady brass that's all I could find. From what I heard that may not have been the best choice but I didn't have much choice. Any information would be appreciated thanks.
