Who/Where to get the best prices for a set of shellholders?

I agree. Having them all from the same maker eliminates any slight dimensional differences among them.

I discovered that there are such differences between brands when I substituted a Brand A shellholder with one from Brand B once. The headspace changed on sized cases. Unfortunately, I didn't discover that until at the range - none of the loaded rounds would chamber.

Now I keep a shellholder in the box with the dies for one-of-a-kind sizes. If I have more than one cartridge that can use the same shellholder, I make sure that use the same one for all those rounds.
