Re: Which seater die?
For a hunting cartridge my recommendation would be a Redding "S" type Full Length sizing die and a Forster Micrometer Seating Die.
The Redding allows you to control neck tension from light for single shot rifles to tight for repeaters with any brand of brass by changing bushings.
The Forster allows you to control seating depth without spending a long time fiddling with the seating stem and lock nut, and if you keep good notes switching to different bullets is as simple as readjusting the calibrated knob.
