In a previous post an incorrect SKU # was listed for a knob which can be used on the Dillon powder measure. This knob can be found at Home Depot, or can be special ordered by Home Depot. Here are the details:
KNOB - FLOWERETTE 5/16"
DR# - 24BIN - 1
Dr# - 971
SKU# 030699837489 (corrected)
Crown Bolt Inc.
Cerritos, Ca. 90703
This knob press fits onto the dillon powder measure adjustment bolt and it works perfectly on the 550B that I just bought from Brian. BTW, Brian's prices on dillon products beats everyone else I could find on the Internet. I also bought the dillon electronic scale and I am very pleased with the accuracy and the speed in which it weighs the powder. I will NEVER go back to the slow clunky mechanical scales. If you do not have one you don't know what your missing!
