Okay really it's with the powder measure w/in the RL550 i guess. Anyway, here's the problem. I inherited a RL550 with some old and broken parts. I replaced parts and can crank out .223 loads using extruded powder just fine. They are within 0.2 gr of target amount, which is fine for my needs.
HOWEVER when i switch to 300blackout, using fine powder (lil gun) i get completely inconsistent loads from 3gr to 14.3gr (trying to get 14gr). To speed up the caliber conversion i have a separate tool head and thus also a separate powder measure. It's still issued by dillon but it's different physical. They both have a LARGE bar... why is there such a significant difference in inconsistency??!
I guess... the first thing i should do is switch powder measures to see if it's powder, brass, measure related. I SUSPECT.. it's the measure but i've got no idea what would be wrong with it to know what to replace.
