I have lots of die sets.
In some cartridges, like 223, I have a dozen different dies.

I recently started 260 Remington, so I could follow my preferences.

So I got a Set of Forster dies and a Lee Collet die.
I take off the Lee "O ring and lock ring" and put on a Forster "Cross Bolt Die Lock Ring" so it will slide in and out of the co-ax press. I take the Lee Collet die apart and polish in the lathe; the tapered outside of the collet, the mandrel, and the collet sleeve.
I usually send the Forster sizer die body back to Forster and get the neck honed out a few thousands to my specifications for $10 + shipping. Their Hardinge collet lathes are faster to get the die centered than my gunsmithing lathes.
Most any new bottle necked rifle cartridge I might start reloading, 260 or anything else, this would be my choice.

There is probably someone out there that can reload better than me and shoot better than me with ANY dies he uses vs me with my favorite dies, but I know what I like for concentricity, brass life, avoiding trimming, avoiding annealing, and convenience.
