How many of you use the press to insert your primers vs. hand primers? Thanks!

Re: Priming with the Forster Coax press

I do not use the priming feature on the top of my Bonanza co-ax or my Forster co-ax.

I use a Forster priming tool.

I load the tubes with an RCBS primer tray lid milled out for the thickness of the bottom of the tube. I clamp the tube to the tray lid with a clothespin type clamp.

I use the RCBS Universal hand primer (with the square tray and co-ax style universal shell holder) to prime instead of my co-ax. Just quicker and easier.

Re: Priming with the Forster Coax press

I prefer the Lee Autoprime for priming everything that doesn't go through the progressive. Priming by press just doesn't let you "feel" the primer seat. This can cause many of the "crushed" primers you see in handload boxes. The stress I use to prime is contained in 2 fingers and thumb on the Autoprime tool. For my money probably the best $10 you can spend on anything LEE.
 
Re: Priming with the Forster Coax press

I actually like to prime on my Coax but it's the only single stage press I like to prime on. I can feel the primers seating on the coax but could not on my Rockcrusher or Redding Big Boss. I also have the RCBS hand primer and use it when I am priming over 50 cartridges at a time.
 
Re: Priming with the Forster Coax press

Not sure why anyone would be concerned with crushing primers on the press. It seats them ALL .005 below flush. As long as you do your part and load the primer correctly and smooth motion on the press handle it's a non-issue.
