On a typical progressive Dillon Precision Press comes a powder thrower with a hex head adjustment screw. If you are constantly making changes to your powder thrower this becomes a pain using your wrench every time you want to make an adjustment. To make this easier you can replace the hex head screw with one that allows you to quickly adjust the powder thrower without tools. This replacement screw has a nice sized plastic knob with laser etched graduation markings and can be found from Taylor-Tactical-Supply.
Each finger adjustment screw comes with a slightly thicker washer than what came with your Dillon Powder Thrower. When installing the screw you can use the existing washer and wave washer (tension washer), or use the new one to get the knob tension to your liking. In some cases you may need to use both.
The screw will work on both the large and small powder bar found in your Dillon powder throwers for the 1050, 650, 550, SDB and 900 reloading press. You can get yours at Taylor-Tactical-Supply EBAY or Amazon
