RCBS SCALE CHECK WEIGHT SET - STANDARD - SKU: R98991 Reloaders rely on their powder scales to accurately weigh safe powder charges and check the charges thrown by their powder measures. Correct readings are essential to safe reloading. Although RCBS reloading scales are designed and built to provide accurate readings, they should be checked at the beginning of each loading session. If the scale is not covered, dust or bits of grit can accumulate in the bearings and go unnoticed. The result can be an inaccurate reading. A quick check with accurate check weights for the range being used will assure the scale is providing correct information. The RCBS Standard Scale Check Weight Set has enough weights to weigh 60.5 grains when they are all combined. Ideal for handloaders who need to check the scale enough to ensure powder charges are accurate. For those needing to check a larger range when sorting bullets or cases the 510.5gn Deluxe Set is recommended. The Standard Scale Check Weight Set contains: 2x 20 Grain 1x 10 Grain 1x 5 Grain 2x 2 Grain 1x 1 Grain 1x 0.5 Grain
