RE: electronic scales
Let me ask, " how happy are you with your powder measure" ?
If you have questions about it too or if you weigh the powder for each load, I highly recommend the RCBS or Pact (it' s the same units made be Pact) electronic powder measure & dispenser units. They link together through an IR port and make accurate loading fast & simple for around $300 (the Pact is usually a little cheaper). Lyman has just come out with a comparable unit (the 1200DPS I believe they call it) that dispenses & measures in 1 unit and runs $20 to $30 cheaper - and it may be a little quicker to set up (not that the Pact/RCBS units are, because they' re quick too).
The Pact system is what I upgraded my Lee Scale & measure to......and life has been sweet ever since. [8D]
