Ok...
I'm here.
I've been shooting and reloading the 376 for over a decade.
I've taken many deer and pigs with it.
It's a round that produces around 4k pounds of energy on a carbine length rig.
Accuracy from the Steyr platform is sub MOA.
Brass is available, bullets are standard .375, mid burn rate powders work great ( imr4895, varget, ECT).
I'm a big fan.
If there's a drawback, it's that the action is maxed out by the round so loading long BT spitzers won't fit the mag.
My preferred load is a 270 Hornady SP @ 2500 MV.
