I have a Frankford Arsenal DS-750 scale that I really like to use for its convenience. I also have a Lee Safety Balance Beam 100 that I don't like all that much. Both are consistent, but both are consistently at variance with each other. The Lee always weighs a charge as lighter than the Frankford. E.g., today I loaded 38 Special cases with a charge of HP38 that the Lee weighed as 4.2g and the Frankford weighed as 4.3g.
I usually stay at the lower end of the middle for my loads but that .1g variance could be a problem at the extreme ends of the load data. I don't know which one to trust and I am thinking of buying another cheap scale to see if I can get at least two to agree on the weight. The other choice is to spring for an expensive high quality scale but I really don't want to do that. I also don't want to get into throwing charges; I used to do that and went back to weighing each charge.
Is this amount of variance normal or is one or both of them not working correctly?
