It's not a major problem because I measure, charge, and weight each individual case every time. Call me Mr. Anal. It's more of an inconvenience to constantly make adjustments.
I've put approx. 500 rounds through since I bought the kit new.
I cycle the charging handle fully each time. Stop to stop and pause at the top of the cycle.
Is there an adjustment that I don't know about?
Reloading requires a lot of double-checking, so being
anal is actually good. There's two solutions.
One- cut a small scoop to the exact powder weight you use for that
load, and powder type, it'll be accurate within a grain, or so.
Two- Get a better powder thrower. IME, Dillon and Hornady make more
costly, but much better, products.
On a personal note, I don't do as well with LEE as others.
