OK, I tried it.
No joy.
Using a carbide .44 sizing die in my Rock Chucker, I easily ran a lubed .45ACP case into the die . . . until it reached the point at which the solid inner base of the case tried to enter the die, and stopped cold.
I backed off, re-lubed the case, and tried again. Same result.
I leaned considerably heavily on the press handle and tipped my heavy bench off its rear legs . . . no joy.
Decided I didn't want to break anything, like perhaps the carbide ring in my die, so I quit.
Interesting experiment, but I believe I'll leave it to you in the interest of preserving my equipment.
And I apologize for my part in hijacking this thread.

I used to use a Lyman acculine press set up as a hand held press. I'd use the anvil from a Lyman ram prime die set to drive the .45 acp case in, and a wooden dowel to drive the formed case back out. This being a hand held press I put it on the floor, and using my weight leaned down on that press handle.
Yer probably wise not to push the issue, I did bust my Lyman press, and it's a type they don't make anymore.
Here is a post from 2008 on Castboolits site that talks about this crazy idea.
