I have never seen that. I weigh a lot of my charges on a balance beam to compare. Have you contacted RCBS?
They like to have steady temperatures and no breezes what so ever. Plus need to be warmed up. If i know I am going to be doing any loading. It gets turned on first thing in the morning, with a weight on the scale as per the instructions.
Yes I follow warmup procedures and the scales are in a good environment.Typically the charges are within .1gn but they drift. I find after maybe 30 minutes you have to recalibrate.
Also one of them might read heavier/lighter than the other one on any given day.
I have 2 Chargemaster Lites and I don’t recommend them.
They appear to work well generally indicating within .1gn. Unfortunately the scale cannot be trusted. Using an analytical balance to double check charges it’s obvious that the Chargemaster is garbage. The readings drift up to .5gn.
Basically with the Chargemaster you could be put up to 1/2gn and not know.
There's something wrong going on there for sure.
I've had 2 since they first came out and have never seen any drifting in either one. I check the weights on every 5 with a beam scale. I calibrate once at the start of a session, and the calibration weights often show it doesn't need it again for 2-3 sessions after.
I'm curious why you have 2 but you say they're drifting and needing calibrating often?
Frankford Arsenal Intellidropper. No problems at all.
The calibration weights that come with the Chargemasters wont show much. You need a proper scale to verify.
You had some kind of issue going on there, not the scales fault. I always verify a few charges here and there on the CM Lite with a 505 and it definitely does not drift. Changing temps, flourescent light, static electricity, varying humidity, other devices like cell phones etc can all affect electronic scales. With a proper warm up mine has been very consistent.
Agreed. I'm talking about 2 sets of small increment calibration weights that I have.
They vary from 0.50 grains to 50.00 grains.
With the equipment your describing you’d have to be very vigilant to see the error. You probably can’t see variance less than .2gn.
I’m using an analytical balance and checking every round. I’ve played around with these Chargemasters for years and I promise you that you can’t trust them.
I trust it.
I win match - Benchrest score and group with loads made on a Chargemaster.
To me, that all that it matter.
Many Champions did load for 1000 yards score competition with a Chargemaster. If it’s good for them - its sure do for me and most shooter.
Making people believe they need a $2000 lab scale and an electronic trickler set up to make accurate ammo, this is Bull ####.
Any electronic and even beam scale will do and be accurate to make match ammo, heck US Army Shooting team ammo was made on Dillon 1050 with a drop powder measure and they won, at one time or another, won every type of competition in the book.
Making your powder charge .001 grain exact will not make you a better shooter. You need a bunch of quality ammo - practice - learn to read the wind and compete to be exposed to what matter after all - to win and be the best shooter you can be.
Same here works greatI've had an RCBS Chargemaster Combo for several years. Loaded thousands of rounds with it and it works well. No complaints or concerns
I was just looking at a new release from Frankford Arsenal. A 50 round automated powder dispenser accurate to +/- 0.1 grain. Looks like a plastic box you put a tray of cases in and it fills them automatically. I look forward to seeing a video of it in action, but I don't think it will be available for several months.
Anyways, I have been using a Chargemaster combo for years and it works good for my purposes. Much depends on your usage and if +/- 0.1 is good enough for you or do you want to spend more $$$ for the +/- 0.01 accurate ones.
