Triple Poise Operation with 1000-Grain Capacity
The scale has some interesting features, including three poises (weight index adjusters). The main poise goes to 1000 grains, while the medium poise runs up to 20 grains. The most precise small poise spans one grain in tenth of a grain increments. The rated capacity of the RCBS M1000 scale is 1000 grains.

Multiple Reference Pointers for Target Weights
The M1000 also features multiple pointers which can be used to set target weight ranges. This speeds up operations. According to the M1000 Users Manual: “[There are] three separate pointers for easy reading of over and under loads. The center Pointer is what is used when balancing the scale and establishes a ZERO Balance. The top and bottom Pointers represent approximately 1.5 grain above and below target load. The top and bottom pointers allow the user to quickly weigh loads knowing that if the beam pointer is oscillating between the top and bottom pointers the load is within +/- 1.5 grains. Having top and bottom pointers also eliminates the need to move the small poise to check powder charge variations.”
