The weapon shooting a 6.5 round will be nothing but a paperweight if the SHTF!
It’s common enough now, the trick is to have ammo, and keep a m-14 up your sleeve. If you’re shooting for precision though, 6.5 is the way to go. There are a few options for 6.5, but I prefer the short action. Faster to cycle, less can go wrong when it’s hectic.
