Sure you can, though I have die sets for many cal. I prefer the Lee loader for 45/70. If you just load with FTX bullets you probably donít need much else, though you really should have a powder scale. If you get into loading cast bollits, I prefer something a little better for case mouth expansion than what comes with the lee loader. I use the Lee universal tool in a Lee C press, works great. I also use Lees crimping die in this press.
