I use Hornady dies for my 9.3x57 as that make was available and their 9.3 seating die can be used for any 9.3 case. This suitability runs in most calibres, such as a .22 Hornady seating die can be used to seat bullets in any .22 case, etc.

The micrometer adjusting seating stem is nice to have for the small calibre varmint rounds, for recording precise seating depths.

As far as that goes any die make can be used. I like Redding dies as well as Lee.
