I'm having problems with consistancy with my Lee Powder measure. It does great for 6 or seven rounds and then will throw a slightly heavy charge. I go back and empty the offending charges and start again without changing anything and it starts trowing good charges again. These are hunting rounds and I could be OK and probably am but am I expecting to much out of this inexpensive measure? Should I just keep my reservoir filled and keep loading and let the range decide(still checking every 10 rounds juat to make sure a major change has not taken place) and just weigh charges when I want to be more accurate?
