When i put the filler in those same loads, the hangfires went away, and accuracy was greatly improved
(Thanks Larry Gibson).
I was down around the "suggested" 60% reduction area with h4895 when the hangfires began.
80% casefill and up was no problem without fillers with that powder.
I totally agree with no need for the filler with bullseye, reddot, unique, and like powders.
