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.
