What advantage is there going with the 1.60 action vs. the 1.45? Do you have to stay close to the action diameter with barrel blanks?

1. The 1.60 action will balloon less with high-pressure cartridges. (Not that the 1.45 is unsafe, it just has less margin with the same material.) Also, a larger action diameter often has a larger tenon which means the barrel breech itself will balloon less, the chamber will expand less, and brass will be easier to extract. We’re talking thousandths of an inch, by the way, not anything obscene.
2. No, the barrel blank restriction is that it must be at least ~0.15” larger than the major diameter of the tenon to have a shoulder that allows for a good and robust bolted joint connection between barrel and receiver.
Your best bet is always to go bigger stronger more accurate stiffer and future options if you dont short your self. pierce 10x one of if not the best is my suggestion. But of corse my view only the best to hell with the rest.
More meat is good when you’re lighting off a dump truck of powder at 60k + psi.
The big action requires a thicker barrel I believe to get the tenon and shoulder right but I think they recently Changed that action so I could be wrong on that.

I went with the 1.6" TAC 408 for my 375 build and installed a a 36" 1.45" barrel on it.
What size is the barrel tenon on that?
Nice looking rifle.

Area 419 adapter? They make stuff for the tac408 receiver?
No, I was just thinking about it as a reference.
it’s thread to pull the brake on the taper is also 1.18 I believe.
