260 from 243

Rambuster, you are going to need a tapered expander. You should be able to find them available form most of the major reloading die manufacturers. It will replace the one in your 260 die and will make it were you can neck up the 243 brass.
Good luck,

Anthony,

I replaced the standard expander plug on my Redding .260 full-length dies with a TAPERED EXPANDER plug.

Using RCBS lube and a Q-tip, I swabbed the inside of the lapua .243 case necks, just inside the case mouth. I then applied lube to the entire outside of the cases and ran them through the FL die. No problems.

Make sure you ream and chamfer the expanded case mouths after cleaing the cases.

Anneal it

243 to 260 is not a big 'bump` but if
you anneal your case necks first,
the job will be easier and your cases
may last longer.
