I like the 450 Marlin, but I'm concerned the brass supply may dry up a la 338 Federal. Of course, you can make 338 Fed from other stuff, but with 450 Marlin there are no options.
What would happen if you had Savage pre-fit barrel with a chamber reamed for SAAMI spec 450 Marlin but used standard belted magnum headspace gauges (eg: 300 Win Mag) to install the barrel? The difference in belt width is 0.032"--0.220" for the H&H family vs 0.252" for the 450 Marlin. So the case would end up 0.032" deeper into the chamber in relation to the barrel shoulder.
The follow-up question is: Would that allow me to use cases made from H&H family brass cut back to 2.100"?
If it worked it would be sorta like a 458 American, but 1/10 inch longer with maybe ~3-4gr additional case capacity.
