Fast forward to now and shooting has had to take a back seat due to business commitments and now having a couple of children but we still try to shoot the local pennants and every fox I see. So it was mostly out of curiosity that I purchased the SuperTrickler having been closely following its development. Now one thing the SuperTrickler does is make it really easy to calibrate the AnD FX series scales. Its arrival coincided with one of my business suppliers having an offer on 100 gram E2 quality calibration weights which are correct for milligram scales and I suddenly realised that I had no idea of the provenance of the 100gram weight that I had been using since I originally bought my scales so I made the purchase. Well, you guessed it… the old weight was nearly a full gram (906mg to be precise) lighter the certified weight now in my possession.
Kind of knowing what to expect, my next move was to grab a box of 55 grain projectiles and weigh a dozen of them with the old calibration and then reweigh them with the new and sure enough, with the old calibration the projectiles were all 0.5 grains heavier then with the new or more than enough to push me out of the node for my load data and potentially into some hot water with some of my Spicer Ftr loads, rendering years’ worth of data basically useless.
I conclusion, it’s obvious but your digital scales are only as accurate as the lump of metal you use to calibrate them! As always in shooting it’s the little, often simple things that will see you undone such as lose action screw costing you an OPM (sorry Sophie

Have fun and shoot straight.
