I'm gonna need to get a 300g weight to zero my scale, what class of weight do you guys recommend?

Some people think that using a bullet for a scale "standard" is enough for the 1K needs.

I would prefer to just buy a $10 weight and think I'm okay with a a milligram tolerance. I'll Recalibrate using the directions I think, after reading up a bit..

I would even say that example would not make a difference. If you are using a class 1 weight and you were off 0.75mg out of 300 grams, that is an off value that is so much less than other environmental factors one normally have to deal with such as variance in powder, different barrel/bullet/case/primer, different temperature, etc.amlevin said:The only time a Class 1 calibration weight will make a difference is if you are trying to make YOUR readings match someone else's readings. That's when the calibration weight needs to be accurate, meaning the same as someone else's cal weight.
jlow said:I see you clean your "standard" masses. You can do this but in the lab, we NEVER touch any of the calibration weights with our bare hands but use gloves when handling them. The reason is skin oil and salt can get on them and cause weight deviation and oxidation, something you never want to happen to your standards.
