New To Reloading Question

[popgun]

I would get good brass like Alpha or Lapua. I would try stick powders like Varget, VV N150, it's harder to get smaller ES with ball powders. The most accurate bullets in my gun are 90gr Bergers loaded a few thousandths into the lands. Shooting to 200 yards a high BC bullet has little advantage. 6PPC is almost the same cartridge but generally use slower twist barrels but some reloading data may be of use.
