I hope this isn't too much of a newbie question:
How important (if at all) is it to have a check weight set with a beam type scale?
With the RCBS scale that I have, the scale is zeroed by adjusting the foot on one side. It's not even clear to me that you could further calibrate the scale if a check weight revealed it was weighing incorrectly.
While I am a newbie to reloading, in a past life I did a lot of weighing of chemicals in a lab. I only recall calibration checks and adjustments with the digital scales.
I thought I'd check though since I really don't want the end result of bad recollection being a blown up gun or worse. I've looked around a bunch on "the series of tubes" and didn't find much.
