Well, the only long, rifle-type swaged bullets I've seen were made by the Polisars for their Whitworth shooting. They were 595gr hexagonal beauties, and looked far too good to shoot. I still have a few, thanks to their generosity, but I believe that they were not cheap. They were about $1.40 each, IIRC.
Corbin makes any number of different calibre swaging machine dies for either pound-swaging, or mechanically pressed swaging - they are a mite expensive too.
