I bought a Lyman beam scale from eBay but it won't hold zero. It varies at a maximum of .2 grains. I've got a $10 digital I bought years ago that is more accurate, according to the check weights. At this time I think my options are, tune the beam scale and re-check accuracy or buy a new beam scale from a store so I can return it if it's a piece. I've heard beams at $100 or less are more accurate than digitals at that price point. Have any of you guys tuned your beams? Any other options I have?

Been down this road and wasted lots of money trying to save money.

Buy a brand new beam and a trickler and they are plenty accurate and sensitive right out of the box.

I'd give Lyman a call. If they're anything near as good as RCBS, they'll fix you up. I have an RCBS 5-10 that I noticed acting weird back in the early 90s. I called RCBS and they said "send it to us." I got it back in about 10 days, totally refurbished and good as new. I believe Lyman's scale was an Ohaus scale, just like the RCBS scales.

My experience is the beam scale that came in my starter loading kit is more accurate than my chargemaster, but my chargemaster when calibrated has never failed to measure the check weights exactly either.

Try this.
Take a make up brush and windex and clean the small pillow block groves on the base. Blow dry to make sure they are clean. Then look at the knife edge on beam and make sure they are shape and smooth. If not gently clean them us with a whit stone.

The problem is the Chargemaster scales drifts over a loading sessions by up to 0.3 grains.

Once I started finishing powder measurements on a beam, groups shrank noticeably on paper and flyers became rare.

how much of that variance in the Chargemaster could be due to you lights as some stated that florescent lights interfere with electronic scales?

Yup, yup!


I loaded for my new Barrett today, all measured one at a time on a beam scale, trickled to "zero" Going back old school I guess.

Yes, they WILL drift. I re-zero mine after each fifth charge. Keeps it honest.

It happens even in the middle of the day with the lights off.

I use the Chargemaster to throw to 0.3 under the desired end weight, and then finish on the beam with a trickler.

Good luck with the new rifle.

I've been pretty lucky with used scales. Got an rcbs 10-10 and a little Lyman Digital that runs on 9v batteries and both are GTG. Then again the rcbs 505 that came with my set still works too, but it just feels cheap.

There are places to pinch pennies but a reliable scale is a critical piece of gear for a reloader. Either the RCBS or Hornady beam with magnetic dampening will do what it should out of the box. Either can be had new for less than $100. My advice is "buy one and be done".
