There are various little tricks of the trade so to say which will make some things easier.

eg. When setting up/checking pistol loads (usually 2-5 grains) thrown with a powder measure, don't bother trying to get accuracy weighing every case full. Throw 10 loads, and then check the weight & divide by 10, gets you a better average load.

Beware of some of the "cheaper" digital scales (kind they use for coke etc.) some are very inaccurate with No repeatability. A good Beam Scale is better. If you buy a Lee reloading kit; don't even open the scale in box, just throw it away (or try and sell it) and buy a RCBS/Redding/Lyman/Hornady version instead.
