You must use the Lee Liquid Alox
not really....
I'm using mine to seat the gas check and size the bullet and then pan lubing afterwards (w/ 50-50, speed green, Lars red, etc...).
I dab a good bit of Imperial sizing die wax on my index finger and thumb and smear the bullets as I pick them out of my bin and load then onto the post.
The nice thing about the Lee system is that you won't deform the nose of the bullet as they push through from the base.
Also, you get the sizing die, the plastic tub, and a bottle of LLA in the kit..........and........you can use it on any single stage or turret press.
With the lube sizer setup, you have to buy a sizing die and a nose pusher jig thingy....not to mention drop ~$200 for the press.
Don't get me wrong. I'm not knocking lube-sizers and I really want one. But the Lee system gets you up and running for a song.
Check to see if they offer it in .458 or larger for the 45-70.
It's reported to be fairly easy to "beagle" out a Lee bullet sizing die....but I haven't tried it yet.
