I have one of those NIB to sell if you want another.I have a bunch of ways to prime cases. I have the early Lee tools which work well but are slow. I have an RCBS tool similar to the Lee tool but with a universal case holder and a primer tray attached. It is harder to use than the old Lee Tools. However the old Lee tools require Specialized Case Holders and are no longer made so you have to get lucky and find them in a box somewhere.
I recently bought an RCBS bench mounted tool. It is the original model NOT the one that uses the APS Strips but has a Vertical Aluminum Tube that feeds the tool. It is fast, uses normal shell holders, and is totally safe. It is by far the best method I have ever used. I can literally prime 50 rounds in about 3 minutes with absolutely no pain or anguish! The lever arm that activates the tool gives you enough leverage that you could literally stuff a large primer into a small hole. It is an absolute joy to use.
You fill the tube using any of your Vibrating Primer Tube Fillers while the tube is on the machine. Or you can push the primers up thru the plastic tip like loading Dillon Tubes. It comes with both large and small primer feed tubes and large and small primer insertion pins.
Change over is as simple as replacing the tube and the insertion pin and shell holder. Literally one minute.
So easy to use I wonder why I didn't buy one 20 years ago. Read the Reviews online about this tool. That's what sold me.
Midway has them for $77.99 right now on sale. Buy one you won't regret it!
