Hornady digital powder dispenser issues.

[Crazymonkey]

So long story  short I'm having  issues  with my powder dispenser  again.  It seems to throw charges .5 to .7 over no matter  what  I've tried  . Powder  is 4831sc so it should  meter well . I always  run a warm up and calibration  before  I start but it seems  to consistently  drop over charge. It's on the slow setting  as I always  run it there  so it shouldn't  be running  to fast . It's definitely  a bad time  for it to take a crap! I'm heading  back  to unit 27 to help Dan with his son Ajs champ elk hunt on Wednesday  morning.  Dan has his rifle  setup for Aj with  a camera  for him to be able to shoot . I was planning  on bringing  my 280ai  as a backup  should  Dan need to make a shot . The 280ai  is 9lbs all in my 7-08 is pushing  16 lbs . If anyone has a solution  I'm all ears! If not I'm packing  the 7-08.
