Looking for data for new MOA custom 26" barrel 6.5 -284 Norma. Powders i have are: H1000, IMR 4350, RL 22 Bullets on hand: Hornady ELD-X 140gr, Barnes LRX 127gr I know Im reading H4831sc seems to be the gold standard but If I can use a slower burning powder that burns clean and performs well at distance hopefully I can extend the barrel life in my barrel burning long rang hunter/target rifle. Atleast thats my thought process. Ok GURU's help me out. Im in the flat lands so a great magnum powder selection is not readily availible .
