Re: Need some advice on a powder measure
I have no recommendation but just some food for though.
Most measures are better with one type of powder than another. Be it flake, extruded or spherical, and most measure are likely to choke on at least one.
Operator technique is at least as important as mechanical factors when it comes to dispensing consistent charge weights.
I have a Harrells Schuentzen , Lyman 55, Lee Perfect Powder Measure and a B&M. None are perfect with every powder I've use but each of them preform within +/- .02 for specific powders.
It is NOT always that vital to get a charge weight down to the exact tenth of a grain. It can be important in very small charges for very small cartridges, but not in most rifle rounds. Instead, what you want to achieve is ±1% of the desired charge weight or less. For a 50-grain charge, that means anything less than a half-grain either side is not only acceptable, but you probably cannot tell the difference on target.
