That's the best idea I've heard yet. I could get a 7mm Rem Mag neck sizing die (Lee Collet die?) and seldom need anything else. A 300 Win Mag full length die without the expander ball would provide everything but neck sizing, and I would be set up without spending a bunch of money.
How do I determine trim length? Pull a bullet from the loaded ammo and measure with a micrometer?
The 7mmRM Collet die wouldn't work because the case on the 300WM is longer than the 7RM. The LCD's need the entire case inside the die so the shellholder can push directly on the collet.
A regular 7RM FL sizing die should work fine however.
