Lyman 1200 DPS III Electronic Powder Measure by Chris Parkin


I had a play with a Hornady electronic powder measure a couple of issues ago – and really liked it. This month, Chris Parkin has a look at the Lyman version. Both are available from Hannam’s Reloading and we thank them for the loan of these measures for testing.


The Lyman DPS III is the latest version – designed to overcome minor flaws noticed in models I and II which Laurie Holland used in a previous article on powder scales. These were mainly comments about powder dispensing speed and the final charge-weight accuracy along with reports of the scale `drifting` over a reloading session. The whole


point of these tools is to speed up reloading with no penalty in charge- weight accuracy and to side-step manual trickling which contrary to popular opinion, has the hidden peril of not countering balance-beam damping - ONE kernel will not move most balance beams.


The DPS III incorporates an electronic powder weighing scale and small pan with an automated trickling tube so when the powder hopper is filled and a charge- weight is keyed-in, the unit begins to trickle at speed then as it approaches the full charge weight, slows down to dispense the final few kernels, advertising accuracy to +/- 0.1grains. A large keypad and display-screen are integral with the one-piece unit to permit data entering. Several small tools are included (more of which later) along with a calibration weight. The powder reservoir holds over 1lb which should be enough for most occasions and in fact, the overall package is nicely made and well presented.


30 minute warm up


After reading the concise instruction book I assembled the measure and plugged it in (via an awkward 2 pin European plug!) for the recommended 30-minute warm-up. If you are in a hurry, this step can be overridden but the instructions do warn that it helps all electronics to warm-up and stabilise. The scale
