Hey everyone, I am fairly new to reloading and I just purchased a vintage, but in like new condition Lyman 55 powder measure. I have used the graduated marks and adjustment screws as directed in the instruction manual, but the problem I have is that somehow after setting these screws and the drum to the proper load, I can dump 4 or 5 charges all weighing the same amount and then the next charge comes out about 1.5 times more than my set charge, or just the opposite happens, I get less than the set charge. Anybody else have this problem or is it just my ignorance causing this problem.

Any help would be appreciated. Are you saying a 50% difference in charges, or a 1.5 grain difference? If truly a 50%,difference, something is really wrong, a big mistake in setup, or a piece is missing, or broken, or a part very loose.

A 1.5 grain variance is not good, how far off depends upon chg weight, but not as bad. Pertinent questions - Rifle or pistol? Target charge weight? Type of powder?
