There's a recent thread here about swaging tools. The RCBS bench tool works much better than any other method I've used.
If I still have the stinkin' press mounted set, I'll make you a bargain in it. Get a bench one.
I use the exact one Chuckdog has pictured. It works great, quick and easy set-up and adjustments are simple.
Never tried anything else and don't see the need to after using the RCBS. It's a great tool at a reasonable price.
