Do any of use guys use this press? I've had one about 10 years and it's loaded a lot of handgun ammo. I have never had a problem with it except for the Lee Safety Prime contraptions. Mine has never been reliable and I have studied videos and read and re-read the instructions. Mine are the old-style with round primer holders. I've been told that the newest ones that are triangular are much better. Am I the only one who has problems with the old round rones?
