[QUOTE="1Moose, post: 2369736, member: 74044"] Thanks Mike, in my "pre-reading" before starting on the neck-turning adventure I also saw that the relative sizing between expanding mandrel and turning mandrel was critical, so I got both of them when I ordered the Sinclair 4000 turning kit. The fit on the turning mandrel wasn't as tight as I thought it might be based on reading people describe that it should be "tight," but the expander mandrel does measure only .001 larger than my turning mandrel. The case spins freely for me, but I thought it might be more snug. I get the tiniest amount of play in the case when it's on the turning mandrel. Perhaps it'd be even tighter if I annealed the cases before expanding them (I just got an Annealeez annealer and have yet to set that up to use). I get this same minimal movement on new brass that I expanded with the expander mandrel, and I'd think that brand new brass wouldn't need to get annealed before expanding, but I'm just learning all this from scratch. I'm going to look to see if more precise case trimmers are in my price range given all my current expenses. [/QUOTE]
