I have an RCBS two die set and then bought a Redding neck die. I use Lapua Brass exclusively now but have also used RWS and Norma brass. I had no problems finding a sub MOA load in 286 and 320 Woodleigh projectile weights.

I haven't used the F/L die much prefering to only neck size virgin and once fired brass.

For a short range thumper hunting round like the 9.3x62, I don't see the need to take as much care with case prep as I would with a varmint calibre. My rifle is an ex. 30-06 and has no problems feeding the neck sized euro cases.
