I have a number of rounds to load for a Prairie Dog hunt later this month. I'll weight each load but, figured using a friend's Lyman DPS 1200 would be the hot ticket and a real time saver.

Went over this morning and the best it could do was stay with in .1 grain. I'm using an extruded powder (RL15) so it's not as easy to meter as Ball or Flake but, given that this was more of a trickle than a thrower, I expected more accurate metering, basically hitting 39.0 grains every time.

In checking the first dozen loads I found it to be 39.0 -39.1 when checked on a 505.

Am I expecting too much, or is this just how electronic powder measures are ??
