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.
I also load and shoot the 376 Steyr.
Its a thumper.
Due to the nature of the terrain that I hunt, I want something that thumps, and if the critter is not DRT, then two leaky holes allow for a blood trail a blind man can wade in, yet due to the MV, meat damage is not usually a factor.
My go to load is the 235 Gr. Barnes TSX over 65 Gr. H4895
In my Steyr the OAL is pretty much limited to 3.1" due to the dimensions of the magazine.
ya!
