ok so I remember reading load development for this caliber on this forum but cannot find my way back to it. I bought Lapua brass, 143 ELD-x, H4831sc and federal 210. Hornady didn’t have info on this bullet in load book? So to start what grain and cartridge overall length should I begin with? I know there are a couple of you 6.5x284 guys on here that know your **** and could save me some wasted bullets in development. Gun is Christensen ridgeline, 26” barrel 1/8 twist. I can switch up powder and primers if need be but this is what I picked up to get started.
