I have had the Chargemaster 1500 since it first came out (can't remember the year), and have loaded thousands of rounds with it.
I have noticed it drift a bit from time to time but just re-zero and good to go. the only issue I have had is a strange one...........the second row of numbers on the pad 4,5,6 very seldom come up on the display as 4,5,6 the first time. for example if I am trying to load 25.0 grains of powder the display will say 22 several times until the 5 kicks in. kind of annoying but not worth getting a new one over, and yes RCBS has confirmed it is way out of warranty !!!!
I think Jim Conrad had an issue like that with his. I could be mistaken as to the nature of the problem he was having, but give him a shout...the effort might pay off for you.
