I don't know about the new priming system on the Classic Turret, but I had to use the priming system on my old turret for the first time and it was not something I liked. I use the Lee prime, but I did not have a shell holder for my .500 S&W, so I used the one on the press. I am used to the feel of getting a primer properly seated with the Lee. I have never had a fail to fire. Using the press, I had 4 out of 6 fail to fire. Part of that, may have been that I used some old primers, but I quickly ordered a shell holder for my 500 anyway. $2.16 is a cheap price to pay for confidence. (I also threw out the old primers)
