I need to crimp 20 ga brass huls loaded with slugs. Any idea who makes a crimping die for it?

Are you talking about a roll crimp tool? If so Balistic Products ans Precision Reloading sell them.

No, I have one of those , they does not work with the brass huls.

Duhh! Stupid me I missed the part about the brass hull. I'm sorry I have no experiance with those.

Yes, it seems dificult for caliber 20. For caliber 12 RCBS make the cowboy dies. 12 is the only caliber they offer.

It would seem like you could have something made like the Lee Loader for shotshells.
How much of a roll does it need? Are you useing the Magtech brass cases? Is there a wad ontop of the slug, then roll crimp over the wad?

Anybody have a 20 ga Lee Loader they could take measurements from? I wonder if it would work without haveing to make something custom?
