Thank you for that data. I picked up the powder, dies etc this w/end. I’m going to try 139g Lapua Scenar bullets. I’ll be loading up this week using .2 increments from 41-43g hopefully to find a node that I can work from. I’ll start with the Hornady brass that I have using large primmers. I have to ask: what is the advantage in using smaller primers for this caliber?
