I'm a little late saying anything about my Frankford Arsenal Hand Primer, I was disappointed because it had less feel than my older RCBS bench priming tool. I also had problems with the shell holder for the .44 Special -.44 Magnum that would not hold the rim of the cases.
So I went to the hardware store and found a lighter spring so that less force was required to squeeze the priming handle to get more feel. And then found out and ordered a .44 Special shell holder for the Lee hand priming tool pictured below that fit the Frankford Arsenal Hand Primer.
