Agree, CAS needs aren't the same as a hunter's needs.

The '73 is the fastest, ctgs moved into the chamber parallel, not at an angle. The toggle link action is the weakest.

The '92 is the strongest, but not necessarily the fastest. Rounds have to enter the chamber at an angle, are prone to stove piping, most COAL sensitive.

The Marlin is somewhere in between, stronger than the '73, close to, but not as strong as the '92.

A slicked up Marlin can run pretty fast, not as fast as a '73.

Heavy walled brass, like .45 Colt, doesn't do that well with low powered CAS loads, are prone to blow back. The thick walled case at low pressure doesn't expand to seal gases from blowing back. The chambers have to be loose enough for a bullet to chamber at an angle. I took my Marlin Cowboy .45 Colt out of CAS, loaded 300 gr. bullets over a max dose of 4227. A real 'diller killer, no blow back.

Here's my custom, short stroked .357 '73 carbine. This is about as good as it gets for CAS.
