I am making up loads of three rounds each using H-414 and H-4831SC for my .375 Weatherby. I didn't want to use my electronic powder dispensor as cleaning it up for the two powders would be tedious. So I took out a very popular orange plastic scale I bought a few years ago, set it up, balanced it then went to check it with my check weights. It keeps reading different for different check weights and placing the 10 grain weight got two different readings. Time to throw this scale out. And the dang thing is new too. (:
I am using a Redding 325 grain scale made sometime in the '50's. It is spot on after I balanced it and checked the repeatability with my check weights. Only problem is the thing takes forever to settle. I can live with that for this run. But now I see why the manufacturers went to magnetic dampening. I tried a couple drops of oil on this Redding, doesn't help. At least I know that 76 grains weighed out is really 76 grains.
The old stuff still works perfectly. Now I wonder how much the thing will be off once I pretty up the balance beam with some Brasso?
