well i did that "trick" to expand the large and small primer plastic "pusher" and it works great frankly.I have been using a dillion since 1987 and its been bulletproof.
I decided to give the new 2023 "improved" lee pro1000 a try. I can not get this machine to load more than 20 rounds without it dropping a primer causing me to stop everything and retrieve the primer because it get stuck under the press and you can't put the ram all the way down or flip the primer and put it in backwards. It now sits in the corner and will probably never be used again.
however, i am not really terribly fond of my Lee, i "just like it" enough to load my 9mm's.
when i can afford to do so..??
i'm gonna buy another 550c, and the roller handle, and the bullet tray.....i got everything else.
the "Lee primer trick"......and it works..!!!!
