Thread: What's up with my scale.

I've got a Lyman 1500 electronic scale. Had it for a month or so. It's supposed to be accurate to .1 grain.

Tonight I was weighing 139g SST bullets.

The weights were all over the place....and that was with a single bullet. 138.8, then 139.2, oops, up to 139.3 now. Lift bullet off and sit it down again...now it's 139.0 or 139.1, slowly switching back and forth. Over and over again one pill and different weights.

That's not .1 grain accurate as advertised. Any suggestions? Are they all like this? Do I need to drop more coin.

After measuring about 50 bullets the distribution was visible. Lots hovering around 139g give or take .1 and fewer out at the margins, ranging from 138.6 through to 139.4. Strangely not many at 139g. Twice as many were .1 higher or lower.
