I generally use Redding dies (or Forsters) for my rifle reloading.

Redding makes a tapered expander. Take out the expander, install tapered expander one caliber larger and open the necks. The adjust FL die until you get chambering in both rifles. I do this with belted mags to eliminate the no-headspace stretch on the first firing.

Or fire all in the one gun and partial FL size and set the die so ammo works EVERY TIME in both rifles.
