Funny how we get to know the equipment we use. To me, the 30-06 uses the #3 shell holder (RCBS). And still one of the most used, regardless of brand.
Yeah, these are the shortages that don't make sense to me. It took me a while to find a press (needed a bigger one). Just have to be patient and use the "notify me" option some of the suppliers have.
I will say, the quest to find some of this stuff has revealed a number of smaller(?), at least lesser known (to me) suppliers. Some of them have been able to fill a need quicker, probably because of less traffic. Most are niche sellers primarily, as opposed to Natchez and Grafs for instance.
