You are a typical milsurplus shooter.
You have a small wad of money on hand.
You have a couple of choices but the current political climate has you concerned.

What comes first guns or ammo?
I have enough cash to afford another nice milsurplus rifle or a good size batch of ammo.
I already have several rifles that I do not have a good supply of brass for. The best way to acquire the oddball brass they require is buy the loaded ammo and save the brass.

Question:
The question is do I:

Buy another military rifle that shoots oddball ammo and have fun and worry about brass later.

Buy another military rifle that uses easily found brass.

Buy the new ammo for the rifles that I already own.

Choices:
Buy the rifle that uses oddball brass and worry about it later
Buy a rifle that uses easily found brass
Buy the ammo (eg brass) for the oddball rifles that I already own
