RE: Using the RCBS 5-0-5 scale...
 

I almost never use my 5-0-5 scale since I bought the digital. I always check my scales zero with a set of scale weights. I was told by my grandfather (almost 40-years ago) that balance beam scales can get "sticky" and give you an false reading. He always checked his scale with scale weights.
A friend told me Jack O'Connors scale was off by two grains and Jack never knew it. He said some editor wrote this in one of the hunting magazines. I guess someone was using Jack's old reloading setup & checked the scale with scale weights.

I can beat anyone speed wise with a beam over a digital. They update real time. Wolf, I suggest you give it a try. I have looked at all the digitals. I mean all. They don't stay calibrated. Sometimes can't be trusted. If you got a breezy place or even a dryer running, they can fluctuate. And now I find out that mine is accurate within .05gr. Nothing more I could ask for.

I read that that digital scales actually measure the density of the powder rather then by actual weight but give you a reading in weight. and that even the vibration from a neon light can cause a false reading. I bought a Dillon precision eliminator scale I couldnt ask for a better beams scale its dead on within .1 grain with my check weights and even using some bullets for check weights everything is within .1 grains. I would have to say it is the most consistent scale I have ever used. Besides I was told a scale is only used for reference since you will be working up your load anyway looking for signs of pressure. Someone even said that even if the scale only measures within .3 grains it doesnt matter because you should be working up the powder charge anyway from a start load which should be considerably lower the the max charge. To comment bigcountry I figured I prefer to trickle my charges for every cartridge and I couldnt do that with a digital scale.

I've been using one of these scales for years now. A good accurate scale. Just zero it out before you start (level it up).
I set mine on a home made shelf made of 2"x6" boards for the sides and a 2"x8" for the top (so I have room to put my trickler). This puts the scale more at eye level when weighing my charges.
