Lyman 1200 DPS III


Electronic Powder Measure by Chris Parkin


honest, the older balance scale was hard pressed to notice a difference on ANY load. Occasionally, the Lyman would sound a warning beep - which alerts the user to look at the screen - displaying an over- charge warning if it drifted more than 0.2 grains and during longer reloading sessions, paranoiac had me mechanically re-weighing random charges just to keep my eye on things.


The instructions warn you to be wary of temperature changes, air currents and local static or magnetic interference which although logical were not a problem, although if something did upset the unit, a `Re-calibrate` warning sounded. A clear folding cover can be lowered over the scale to exclude draughts but I didn’t use it, believing the less I touched the unit, the more reliable it would remain.


I was careful to check on production times and a charge of 43.4gr of H4350 took 22 seconds on average to dispense, 22gr of H4198 a similar time and a large 80gr charge of H1000 was running nearer 35 seconds so no problem there. I chose to seat bullets on my bench simultaneously to dispensing powder but although my bench is very solid, I never performed the seating at the instant final trickle was taking place, better safe than sorry. The automatic setting means every time the pan is replaced, trickling recommences.


Apart from kernel spillage on commencement of trickling, the biggest downside was emptying the measure/cleaning when finished or changing powders. A small hatch at the back with an internal shutter started out easily, pouring the powder hopper contents directly back into the bottle. After this, quite major disassembly is required (hence the brush and tools) to remove every last kernel from the complex internal mechanisms and to do correctly, was a ten- minute job. Not the end of the world but a major downside relative to its competitors.


The powder emptying shute worked well but then dissasembly starts


Make sure you close it after emptying!


The trickling tube needed removal to thouroughly clean it


The supplied tools and pan, note the optional plastic funnelpan would not operate autorepeat although it stopped spillage
