Many thanks to everyone who answered my questions.

For my .243 Win die, simply turning it 100 degrees or so and crimping three times did the trick.

I just got a .270 Win collet die -- the three crimp treatment did not work. For that, I used some fine emery cloth (400 and 600 grit)and a drill, and took .002" off the mandrel. That with three crimps did the trick. Even with three crimps, it's nice to not use messy case lubricant.

Thanks again to all for your help.
