So I am wanting to shorten the barrel on my CZ 452 Varmint. I have heard these barrels are a beast to get out of the action. My question is if I stripped everything off the action (trigger, mag housing, bases, etc.) until it was nothing but the rounded action; if I stuck this in the lathe, would it hurt the accuracy of the barrel vs doing it the traditional way? If I go ahead and indicate my zero off the bore of the barrel would it hurt? As long as I did in fact get it dialed into zero before I cut my crown? Does anyone see any issues with this? Thanks, and I apologize if this is a stupid question!
Gunsmithing Barrel shortening question? Might be a dumb question...

I did something similar with a Mauser I just got done with. I put the action in the chuck and used a steady rest on the muzzle end. Dialed off the bor and cut away. I kept the rpm really slow . Went slow and light cuts . No issues I could see or tell shooting. Good luck
Sorry I should clarify. My steady rest is a small 6" rotary table that was modified by an old timer to act like a second headstock kind of . Think instead of steady rest more like a chuck on an three way adjustable base with bearings so it rotates with the work. Up and down, left right ( for tapers I think) and length are adjustments along with the four jaws . Works really well when I need to use it.
The other way is to use the outboard side to center the action and use the chuck to dial the muzzle end

Interesting. Is that a home-brew item? I was thinking you could probably make a small spider-block and run it in a conventional steadyrest.
That's nice unless you've got a 24 inch spindle and another 6 inches of chuck like my SB13 (I guess I could stuff a 46 inch barrel in there like they did in the link).
I would do it that way, but the headstock on the lathe that I will be using is too long. So I will have to either build something to snug the action into the spindle or hold the action in the chuck and use a steady rest.
Does anyone see any reason why accuracy would diminish? It should shoot as good if not better if it is done correctly right?

Accuracy should not be affected . Your load may need to be tuned to the shorter barrel length.
The set up was built by the gentleman I bought my lathe from. He had a milling rotary table where the gearing crapped out. He build new bearings for it ,ditched the base and it is now a "chuck steady adjustable super duper high speed low drag shade tree rest"
I think the idea of a small spider inside a steady rest would have been easier to use some days.
