That one caliber you bought a gun for but can't find ammo

[Alan]

I picked up a rifle in .300 Blackout last year because I got a good deal. Problem is I've only found ammo for it twice and it was expensive both times. Gun just sits there looking pretty. Anyone else buy something and then realize ammo's impossible to get?

I bought a 6.5 Grendel on a whim, and then I spent months struggling to find ammo for it. Before I buy a gun in a new caliber, I check to make sure I can actually get ammo for it. If I can't find it regularly, I don't bother buying the firearm.
