Smokey Joe--you do seem to be in the minority here.
I have been reloading for over 20 years and never had a problem with the original Lee Auto Prime and I never have broken any parts. I like it because I can seat the primers deeper than I can with the old Rock Chucker press primer attachment.
But this new Auto Prime XR has been trouble from day 1 for me.
The primers get out sync with that flip one out of the tray before it goes into the actual priming spot. And then often I cannot press the primer into the case--it seems to be a little out of alignment. This seems to happen 1 out of every 3 or 4 primers. I never know with their new "improved" system if I can hold the tool perfectly level--tilted forward or what? I am not a patient man and although I do load single stage--I don't want to waste time being aggravated by this priming tool. I have my original Auto Prime all set up for my calibers that use large pistol primers. And now I have gone back to priming on my rock chucker for the calibers that use small pistol primers, instead of using the Auto Prime XR.
Anyone own the RCBS hand priming tool? Is is good. Perform pretty flawlessly?
