I dont know if that old 9ton press would generate 9 tons or not.I know at times I had to put a cheater on the handle and all thet would do was fragment the nose punches.
I guess if you can make adapters to fit the dies and nose punches to fit a arbor press, I dont know why it wouldn't work. but I would guess you would have to go with the heaver hydrolic dies If you figuring on using more force than what the wallnut hill press would do. Why not just go with a good press?
I will tell you swaging is time consuming,and you can buy a lot of bullets for the money you invest in swaging equipment.I started dooing it at a time when you could'nt buy a large .458 or.459 diameter jacked bullet so I had to make my own,and I still do I enjoy doing it,but if you want to save money doing it the payback is a long way down the road.
If you really want to do I would call Richard at RCE and order what you want.If you want more force get the hydrolic press or convert one.
I cast more bullets then i swage I have enough moulds for just the .458 and .408 to start a used mould businessand some I wich I still had I used to have a old Ideal Perfection hollow base adjustable 7 lube groove mould I dont know what ever hapen to it,I guess I loaned it out and it didnt find its way back home but it shot better than any of moulds I have now.I guess Cat Whisperer what I'm trying to say, a good cast bullet is just as good as a swaged bullet unless you want a special bullet.Lp.
I forgot to mention a lube die would fragment if you wanted to use one ,and asfar as more force, swaging a .458 is no differant than sizing a case in a loading press
