You will never hurt an RCBS press if used correctly, I recently sold my father's rockchucker to a buddy looking to get into reloading cheap. That press was built in the late 60's-early 70's and still runs like new. My rockchucker circa 1996 or still turns out ammo like the day it was made, I've never had a problem with either press. RCBS customer service is second to none, I've called them a few times to order parts and they've never charged me for anything. Last thing I ordered from them was for a primer pocket swager I got from a friend that was missing parts, called RCBS and explained that I got it used and they sent the parts free of charge. Just an awesome company to deal with, not enough good things to say about them.
