My old Redding powder measure had turned a bit sour, the reservoir was badly discolored and had become pliable to the point that the two set screws were not enough to hold it in. A few rounds of masking tape held for a while, but ... so bit the bullet and ordered in DramWorx reservoirs. Certainly not cheap, but are just lovely. Got on for my old 55 and the Redding. Installation took about 3 minutes for the pair of them. Non-reactive to powder, clear as a bell, built in baffle, nice tight seal (top and bottom) with "O" rings. Took a bit of the fuss out of managing powder.
