Got a new Christensen arms mesa rifle. And need some info on load development. Hoping to shoot burger 300gr elite hunters with lapua brass, h1000 powder, federal 215. Any info about this would be great thanks
Start at 89 gr. .005" off the lands. Work up. Most see pressure from 90 to 92 gr with H-1000 and a 300 Berger. Typical seating depths should be from touching to -.040" off lands.
