I've been using the electric RCBS charge master for about 5 years but I think mine is losing its accuracy. I calibrate it almost every time I use it with the weights but the last few trips to the range I've had some huge standard deviations. (Over 100 fps) I put a load weighing 78 gr on my acculab scale last night and it was .4 higher than what the RCBS said it was. I love the speed of the electric but need something with more precision. Ideas?
