I am thinking about getting a powder dispenser like the RCBS Chargemaster 1500 for handgun load development. The idea is to start out, for example, at 5.0gr, then do +0.2gr increment, load 10 rounds on each measure. I have two Dillon RL550Bs, but don't own any single stage press. The closest place I can run a chrono is about 30 miles away. Given my situation, is it worth to spend ~$300 to get a powder dispenser? Thanks.
