Whether its temporarely out of stock or gone for good, I dont shoot whatever I cant replace. If you cant find stuff for a particuler gun, dont shoot it.
If what I need comes back on the shelves, then I'll start shooting that gun again. I dont think its very smart to shoot up your ammo when it might not get replaced for 6,8 months, a year or longer. You might be low or out of ammo before you can replace it.
That being said, I could still shoot and reload for a long time if need be. I'm just not going to until components are back on the shelves.
Like someone said earlier, I like to reload as much or more as I do shooting it. Most of my stuff is already loaded and I dont want empty it yet.
I am able to shoot just enough to keep the nerves settled.
