Re: RCBS Neck Turner
I use the RCBS unit and it's good. The only real problem I have is the case holder thing often slips--I've thinned the mandrel as much as I dare, which means that if there's no case lube left inside the necks they resist being turned.
My current plan is to get through all my cases and then think about selling it. My rifle just doesn't seem to care about uniforming necks. Got a first-round hit last time at 600 on a 10 inch wide by 17 inch tall steel target, 3 mph wind, hit within 4 inches of the center, so I'm happy enough.
The unit is easy enough to work, no sharp edges, comfortable and all that. The zero-able index on cutting depth is good, but adjusting the mandrel in or out throws it off. Get the mandrel depth down first, THEN zero and set it up. I would prefer the mandrels be threaded into the housing, with a jam nut to lock it in place, so things tend to stay centered. The slide in and set screw setup is inconsistent with the rest of its precision characteristics.
