However, I think that unless your disciplined to make sure the beam is bouncing equally above and below the center or zero line it will have as much spread as any e-scale. Just cause it's off bottom doesn't mean your on target.
My second question was how much tolerance might you allow in powder weight when working up load recipes? Is say .2 acceptable? Is that a significant difference to through MV hence accuracy out?
First. All scales can be off and you should check them with the weights furnished as often as you can.
Some beam scales can drift off due to the dampening system and should be checked.
When I first bought an electronic scale it was off of my beam scale buy over one grain so I made a set of weights for the exact load on my beam scale for the rifle I shot a lot. it varied to dead own to .3 or
.4/10 of a grain so I just thought I Had a bum scale and bought another. It was very consistent but
it also read different than my beam scale so that is why after three or fore E scales I work up the load on my
beam scale and sometimes zero the E scale and dump the beam scale charge on the E scale
to see what it says. this new weight is entered in my loading notes as the E scale weight and it works
the same just a different weight number.
The reason I do this is that in some circumstances a 1 grain difference can totally change the consistency of a load.
Both scales work good, as load as you except the fact that they normally wont agree with each other.
I have some pet loads that are over 50 years old and when they change it is normally the powder batch
number and adjustments have to be made so I use the beam scale as the bench Mark.
And to answer your other question-I trickle each load that has to be accurate to zero 10ths. and measuring
by volume if done right is very accurate but when I try to make every component as
close to the same as possible it gives me confidence (It probably doesn't make that much difference
but I do it anyway).
