Your VC is about as good an action as you're going to find anywhere.
Seems like you found something nice to work with there.
Are you going to monoblock it?
If so, what happened to the barrels?

Great point on regulation and barrel activity when firing.
In all the conversations I've heard or read on the subject, this is the first time I've heard someone speak up to the 'windup' of the double rifle and as with the side by side, how that affects where the barrels point.
That might be one of the many reasons that make the double rifle an easier rifle to shoot than a single barreled bolt gun -- that some of the recoil energy is being temporarily stored via the work of twisting the barrel pair up then springing back...
