I love the .44 special

The term "bean counters" implies money is in play.
It's not the money that is the problem, it is the logistics.

But other than that term, I agree, two different cartridges in the supply chain would be a logistical nightmare.

There is an old adage that states, “Amateurs study tactics, professionals study logistics.”
The origins have been lost to time and it has been attributed to many different people. Regardless of the source, it is very true.

The same folks that produced tanks with high velocity guns and thick armor, all 1300 of them, fielded handguns in .45 acp, .32 acp, .380 acp, .25 acp, and 9mm. I may have missed a couple. I guess logistics matter.

it's the Elgin Gates 375 super mag only in the light pressure version with the thin 30-30 cases.
it only takes all afternoon to make 50 cases so you might as well convert the 375 win's, as go half pressure with the 30-30's.

Some are better at it than others.

Side note, In Michael Durant's book, "In the Company of Heros" (excellent book by the way) he writes about defending himself after his Blackhawk goes down in Mogadishu. He had a Beretta and a submachine gun which both used 9mm. He had a limited amount of 9mm ammo but was frustrated by the thousands of rounds of 7.62 NATO nearby for the machine gun, but no way to use that ammo.
