Yes the hammer method is pretty safe,I am now in my 60' s and survived it.You don' t hammer it like you do a nail head.
You were wanting a less expensive way to go and that was the least I could think of.
As Halcon said you can get the lee kit forbout $70 bucks plus the dies.
I looked in the natches catolog and they do have the original loader for $13.44.I don' t remember what I paid but I know I had to dig a lot of blood root and sang to get it.
Good luck in what you choose and have lots of fun
