Why wouldn't it disappear?
For the fun of the hobby? I mean, I really have zero interest in what you choose to shoot, your choice, right?
Then in reality I can't disappear.
Someone will make custom barrels, someone with make brass, dies, bullets.
Just because noone cooks factory ready to shoot doesn't mean chit.
I run a dead caliber 376 Steyr.
Plenty of brass, plenty of bullets , dies are showing no sign of rot.
