I was gifted a beam scale with the Dillon 450 (it is a 550 now). I’ve never used the beam scale, but keep it for the same reason.I bought a chargemaster several years ago and was initially skeptical, as many had stated that they weren't consistent. I compared each charge to a portable digital and again to my old C-H beam scale, turns our it was both accurate and consistent. Some powders don't dispense that well, clumping together in the trickle phase causing over charges is common with titegroup and 4831SC, but it's very consistent with RL15, N140 and HP38. This is a minor issue though, as removing a few gr to the correct charge doesn't take much time and is still much faster than waiting on the beam scale to stop moving. Loading 1500rds a year would be far too time consuming using the old methods, so for me I will embrace the new technology with open arms, and save the old beam scale for apocalypse usage...
