Dillon 550 spilling powder?

    sounds like it's 'bridging' in the neck of the case.Try tapping the measure or case for a second before withdrawing the case.

    <I am using IMR 4350. that isn't the stuff that clogs the case is it?>

    It's one of them. Tapping will certainly help, but I don't use it in my progressives. At best it's a nuisance & at worst it could be dangerous. One of those powder charge checkers might help warn you of a light or heavy load. I don't have one so I don't know. You might try H-4831SC, I've had good luck with it in my 550B & it's a slower large case powder like 4350.

    H414 powder is almost the same burn rate as 4350 and its a fine ball powder which would meter better in a progressive ( although it's a little more temp. sensitive in my experience ). Might be worth a try...........

    ok thanks everyone.

    I think that is waht it is. When I bring it down real slow it is a lot better. I just bought the powder because it was listed as one of the better acuracy ones for the bullets I wanted to use at a low powder charge (Hornady 65gr V-Max) for my .243.

    Live and learn I guess.

    Also, I know it really depends on the firearm, but interms of bullet seating, is +/- .003" reasonable for a tolerance? I seem to get a variation depending on how quick I close my dial caliper.
