OK here's the take on my new summit rcbs single stage press, set it up and first thing I noticed was primer residue is contained at the bottom of press and never gets near ram or any moving parts. This is the first good feature that is improved over the rock chucker I've used for decades. It can be mounted back from the bench edge flush to bench, I won't call that a big deal but I did take advantage of it, and like the option. Handle was too long, so of course I needed to get the shorter one available. Wife took one look and said why don't it come with the short one standard and the longer one optional? It would work with a really tall reloader or very low bench, but most will probably want the shorter one. The case doesn't move, the die comes down to it, this was different, but ram is huge and after a couple rounds it felt quite normal. The shellholder has both lateral and fore and aft movement built in, the ram has additional lateral movement as well. The same dies I've been using on the same brass are producing straighter more concentric loaded ammo. Not my imagination but real fact, I chose this press from the runout numbers in the large press comparison that's been online for a while now. Another neat feature is a grease fitting on the ram, I'm sure that will get overused by heavy luber's, but a shot of synthetic once a year or every 300-400 rounds sure won't hurt. The ram linkage is adjustable and I tightened one up a little out of the box, again don't look like something you would do a lot but nice to have the option.
Happy so far, and its got features the rock chucker did not have, the rock chucker now handles depriming chores and I will always keep it like an old friend. These improvements are things I appreciate in this single stage press. Cancelled the order on the Co Ax (turns out they never had it) I don't think I'll be needing it now. I'll post if it doesn't hold up, I load 3 to 4 hundred rounds a year with 5 different cartridges and load work, target shooting, and hunting. Rock chucker held up well (19 years) but the primer corrosion going down over the ram constantly has put some wobble in the ram at top stroke. Dave
