Lee balance beam to double check every 10th charge or so. Both are consistantly 1/10 of a grain or less apart. Most of the time they're pretty much dead even. If at all off usually a few flakes off the powder trickler is all it takes to even them up.
I started with hornady 1300 I think (the little one) it works well and does what it says. Accurate to +/-.1gr. None of the reloding scales are that great because most of them are +/-.1gr which leavins you with a total of a .2gr swing from start to finish. I have switched to a gempro 250 jewel scale thats accurate to +/-.02 gr. Its a little finicky but will get loads within .05 gr from start to finish which is plenty acceptable for long range.
