I used an RCBS beam for years. The RCBS came up missing after the move back to Alaska. Got a Lee beam scale. Used it a few times, found it to be hard to use, and very sensative, easy to knock off setting. Found an unopened box and unpacked my RCBS scale.
About 8 years ago I bought the Lyman Electronic Scale with powder feed. Was taking too long to reload, so I bought the RCBS Electronic Scale with Powder feed. Now I work both scales at the same time, loading differant loads. I'll be throwing loads for the 30-06 with the Lyman, and .223 with the RCBS. I measure every load for my hunting, and long range shooting. I only use the powder measure on my progressive press when loading for the Mini-14s and pistol loads.
