I am using the Hornady electronic Scale. I understand this is not the best option but this is what I have got so far. Anyway I was wondering why I seem to be constantly getting better standard deviation with IMR 4064 than with RL-15.

With IMR 4064 I constantly get reloads with a S-D of ~10, and with the RL-15 the SD is about 20, sometime 25-30!.

I though that IMR 4064 doesnt meter well, and RL-15 meter better than IMR 4064. Just wondering what is going on here.

Thank you! :)
