SCORE!! Nice find!
As for scales- the reviews are always hit or miss in digitals. If I went digi it would be a Gempro- almost bought one several times. I went balance for now- with magnetic dampening it is just about as fast as a digital, with no warm up period, way fewer interference issues, etc.and don't have to constantly re-zero during a session (unless I bump it, I will double check it)
I actually bought a RCBS 505 from an ebay store- brand new for about 1/2 the price as most retailers. For powder you are normally only weighing 4 - 80 grains so the typical 1000 gr capacity scale is necessary. Plus I think the smaller the capacity the better it can weigh smaller amounts. Although not marked past .1 grain increments, you can easily see smaller amounts on the needle, which allows you to really dial in, almost to the kernel. (with digital, you are never sure where in the .1 you fall, is it X.19 or X.10 which in can make a difference- especially in precision rifle.As important as a good scale is a good set of check weights. (even if you buy a good digital scale) I opted to go with a pharmaceutical set in milligrams...
and I calibrate at the actual powder charge weight I intend to load that session. I figure there is no point in calibrating to a 250 or 500 grain weight when I am weighing for 5 grains... All the articles I have read say scales are not consistent across all ranges. So setting up at a close to use range is optimal.
A simple conversion to milligrams and I'm calibrating at actual needed weight.
For light target loads I use 4gr. clays and set up with 260 mg of check weights (which is 4.01gr.) Spot on!
