Hi, Im new to reloading and was wondering if it is normal for my rcbs pwder measure to throw inconsitent charges, as much as 3 to 5 grains +/-. one time might be right on, the next might be 3-5 grains over or under. I keep adjusting and never is consistent,so I just adjust with the trickler. Any help would be great.

    The powder you are using may have something to do with this problem. If you are using a flake or ball powder you have a problem with your measure. If you are using an extruded powder the problem lies with the powder choice. Extruded powders do not meter very well out of a powder measure and have a tendency to "bridge" giving to poor drops. I hand trickle for every cartridge that I load when using extruded powders just for this problem.

    A consistent method of operation is the key to repeatable results. Long stick powders can be the most difficult to get set but you should be able to consistently get + or-.01 grains, accurate enough for 99.9% of reloading.

    When setting the charge make sure you have the correct sized drum for the application and do a light TAP-TAP at the top of the throw and a slightly heavier TAP-TAP-TAP at the bottom with the handle to settle the powder.

    What powder are you using?

    I believe my measure came with only one drum. I am using IMR 4831 and I have been clicking the handle top and bottom sometimes seeing a few extra kernels falling out. It seems when I start up with the handle it catches and I think cuts some of the powder. I try to keep a smoothe and even motion

    Buy a Lee perfect powder measure and your woes will go away.

    Lee: Great for extruded powder, horrible with ball and flake.
    RCBS: Great for ball/flake, horrible with extruded.

    I keep both on my bench.

    powder throwers, unless benchrest throwers (Harrel) don't do well with stick powders. I have one for ball powders only, everything else gets run through the PACT dispenser unit.

    I just got my 1500 chargemaster 3 weeks ago and I have found a problem. In the 3 weeks since I set it up the weather here has been terrible and I have now reloaded nearly 500 rifle rounds that exceed 55g minimum per round. The powder is gettin costly LOL.
    O ya the measure is flawless and fast. Can't believe it took me all these years to see the light...
