Thread: Powder measure.

Anyone else have a problem with their powder measure when using cylindrical powder ( AR2208 etc.)? The finer ones ( AR2205, shotgun stuff) meters fine. Mine hangs up on cutting through the large grains and the result is an incorrect charge due to the resistance. I'm currently trying to work up loads for a Smelly MK1 in 25/303 so it's imperative not to fuck up with the low pressures it works under. Tedious weighing each charge though. Perhaps the drum is worn/blunt on this no name brand measure?
