You still didn't answer my question.
What are you aligning the raceway to?
What if the stock is rotated under your plumb raceway?
What if your plumb raceway puts cant in the action-base interface?
I agree with bruce, about what matters when rubber hits the road. And I realize action level in itself matters little, -unless the shooting system is dependent on this.
An example of such a system would be a BR stock riding bags on forearm and buttstock flats.
Here, you need the stock plumb because that's where it will head with recoil, and a bit before the bullet leaves the barrel. You want the action aligned well with this stock level in any way practical toward achieving plumb scope elevation(even more important) also.
So I would think you would first make efforts to level a BR stock, and while in this condition, level the action ring-base interface -while the bedding sets.
Who cares about the bolt raceway itself? It doesn't affect shooting.
I don't 'get it' either. Seems like much ado about nothing.
Ok, final price is $47 TYD Level is not included. I prefer a USPS money order, I can take paypal but would prefer MO. Each will fit the mentioned actions, if you have a question on your actions specifically, let me know. We put each one on a granite plate to check before shipping. Note the rifle below the action is level while the scope base is not. Also we're going to make one out of brass that should come in $10 more
