What sort of variance is acceptable with one of these? He is getting 0.3 to 0.5 grains difference per dump. These are 43 grain starting loads of AR2208 in the 270 for the record.
He asked me and I told him I flat out dont know as I only ever hand measure. I said first port of call is putting the question out there and maybe upgrading to a more expensive model, I think this Lee is entry level?

Powder has heaps of carbon in it which is effectively the same as graphite anyway. Doesn't really matter if it is glass, metal or plastic they are all going to create static electricity until well coated and used.
There is going to be variances no matter what you do. For one you are measuring by volume but really want a result by weight. The volume measures are perfect for Black powder but high quality scales are going to be the go for precise loads to the grain.

But then the 5th time there will be a 0.4 grain difference. Probably because I did something wrong. Or not.
In any case, I feel I can't trust it (or myself) and I weight every charge with my electronic Frankford Arsenal. Just to be sure, to be sure.
