Make note that the 460 is a few thou wider. You could make a wildcat set up to take a longer case to say 2.050" and the 460 XVR factory ammo depending on if a strong action like a single shot action used or just load the bullets out on the shorter case. Note the 60k psi of the 460 vs the 45k psi of the 444 marlin case. Don't go and make a bad boom but you could load down the 460 and not use factory ammo. If you did a 2.050" case the starting pressures would be reduced. Could be a fun project with available dies and reamers. I would call it the 454 Merlin although I would want a strong action like a Ruger #1 single shot for this for load development.

You could make it a straight wall case by turning the neck thickness by .002" providing .004" reduction in the diameter. That would only leave the neck only .0095" thick though which is very thin.

Glad you like.
What are you thinking? A reduced rim necked down 45-70 to 444 bullets or 45 pistol bullets or just a reduced rim 45-70? I liked the idea of a bolt action 45-70 reduced rim +p that would be a modern version of the 45-70-500 that is old nomenclature of a 45 cal bullet, the charge and the bullet weight. The differences between the 45-70-405 and 45-70-500 were that the 45-70-500 was obviously more bullet weight but loaded out much longer and could be great for a short length bolt action with nominal rifle bullets seated out .8" thus an advantage of useable case capacity, any bullets and higher pressure with cheap components not to mention the ability to use slightly altered factory ammo in a pinch.

Here is the 45-70-500 compared to the 45-70. You can see the advantage of a short action bolt action with the longer OAL. BTW I was thinking the ultimate 444 would be opening up the 9,3x74 to 44 cal bullets for use on a 1895 lever action
