It’s not that you under 5,000 rounds.
It’s more important that you 5,000 rounds down.
See what I did there? It’s subtle.
For my ‘battle’ rifle I figure a soldier on patrol carries 210 rounds. I figure in SHTF you can only live through so many fire fights so 2100 rounds is 10 fire fights. The chances of you living through more that 10 fire fights during SHTF? I say pretty close to zero. I would also say if during SHTF you managed to get yourself in more than 10 fire fights you are doing something VERY wrong! Thats my story and I am sticking to it.
