Thread: Seating depth variance between powders

Question for the knowledgeable, if I have developed a load that shoots very well is that likely to be the optimum COAL/CBTO regardless of powder for that rifle?

If I just change powders would you find the optimum charge weight with the new powder at the previous load COAL and write off the power if you don't find accuracy or would you take the best charge weight and tweak the seating depth to try and find accuracy?

Rifle in question shoots AR2208 load into 0.5MOA but have some RL17 to try, normal story looking for a bit more speed!
