I have the Dillon RL 550b and reload 9mm and 10mm for shooting at the range. What are the tolerable variances for the powder measure granins? Sometimes I get up to a 0.4 grain variance between powder drops.
I used a chronometer to measure FPS on different loads. Once set of 20shots showed an Exreme Spread of 69 FPS, one 99 fps, and another 133 fps. On some factory new rounds the extreme spread was 35 FPS.
Is there an upgrade for the Dillon powder measure that would drop more consistent loads? Does this mean anything to me as I just target shoot at the range?
Thank you.
