Quoted:
Be sure your powder measure is throwing the correct charge, before you start loading.
For me I weigh the first 10 or 15 throws before before going progressive.
What I mean is when the powder has dropped and case is in the bullet seating station, I take the case out and weight the powder charge.
Return powder to case, put case back in seating station. Then seat bullet.
Next charged case at the seating station gets it's powder charge weighed.
Repeat and adjust as necessary.
Thanks everyone for the answers. I'll add in a few grains and see where it goes.
What would you say an okay tolerance would be on a progressive? my loads are usually +/- .1gr. Is that okay? Meaning, my 5.0 gr of Titegroup are always between 4.9 and 5.1, but majority of the loads I measure (I also measure the first 10-15) are right on at 5.0 gr.
I've chalked it up to a few grains sticking here and there in the powder drop, a few sticking in the expander and a few sticking in my powder checker. I'm not sure what I can do to keep them from sticking. I've tried cleaning them but it still happens.
