I Have my own reamer and can use any brass out there. I decided that I wanted the existing resizing dies to work with my base diameter and I throated it for 140 VLDs. My reamer is not the best one for a short action though. There are reamers with longer throats than mine too. Neck diameters are all over the place as well. I like .298" for the necks. This is a reasonable no-turn neck. I mostly use Lapua brass. The Hornady brass is not as good. Most W-W brass is not as good either.
