As a teenager, I started with a Lee Loader for my first rifle in '06 Spr. As now, I've got 3 presses: a Lyman Orange Crusher, a Bonanza Co-Ax (about 1977, before sale to Forster), and a Redding Ultra-Mag. The Orange Crusher and Bonanza Co-Ax ( red color not brown), were bought together , used. I got a deal on them in 1993.
The Co-Ax became my go to press.
What I like about the Co-Ax is the ease of die adjustment. And when the die is popped out, the setting is undisturbed by unthreading. With the Orange Crusher and Ultra-Mag, I always seem to have trouble getting the lock rings tight enough to withstand the removal by unthreading procedure. Yeah, I index mark the lock ring and die body, I use proper lock ring pliers and switch all lock rings to the Sinclair Cross Bolt style lock ring.
I was able to update the Co-Ax 'bout 7-8 years back with the high clearance yoke, and both the improved: primer seater, and shell-holder jaw housing.
Given the current prices of new and used Co-Ax, I'm glad I don't have to buy one now.
