Logically one would think the higher the powder charge, the higher the velocity would be right? After doing some more testing last night I have found that's not the case all the time and I'm not exactly sure why. Here's my ingredients: 6.5x284-H4831SC-Fed 210-Norma brass-AMAX 140g Here's my numbers from yesterday. 50.0g shot an average of 2983 50.5g shot an average of 3039 51.0g shot an average of 2861 51.5g shot an average of 2879 Why such a drop in velocities above 50.5 grains of powder? Is it because there's more powder, which takes longer to burn, which in turn will affect velocity? 51.0g shot the best group at .358 but if I can achieve similar results with 50.5 I will drop down to achieve that speed. I will always take accuracy over speed but I do like to test other loads thoroughly until I can prove they will or won't work.
