    I use an RCBS UniFlow and Lee scoops but it seems that the cylndical powders (Varget,H335) measure inconsistently. It's always within 1-2grains but for long range shooting, that just doesn't cut it. It's very tedious to measure/pour each load.
    Do other measuring tools work better or the same?

    MinnMooney,

    Try using the RCBS powder baffle with your Uniflow Powder Measure. I see about +/-0.3 to 0.4 grains with extruded powder. I switch all my loads over to either ball, spherical or flake just because of the variance.

    I have the RCBS uniflow with the baffle inside. I use ball, flake and extruded without any problems.

    I use H335 for reloads in my M4 Bushy.

    MM: I've been using the same Uniflow for 20 years. It's as accurate today as when it was new. For accurately metering extruded rifle propellants like Varget, I don't know how you can get away from using a Powder Trickler and weighing individual charges. Are you having problems metering H335, and which of the two cavities are you using in the Uniflow?;)

    If you want an accurate powder measure that most top bench rest shooters use, get a Harrel.

    Otherwise, I suggest weighing each load, unless you are loading for semiauto pistol and semiauto rifle cartridges of 223, 308 or 30 carbine.
