What would you guys recommend as go-to ammunition, when none of the US made stuff on DocGKR's list is available? I am looking for general purpose ammunition for a general purpose carbine with a 16" barrel and 1/7 twist rate.
For training ammunition, I can find M193 analogies from IMI, S&B, some others. Should I just go with that and call it good? Or stock some of the heavier OTM match ammunition like PPU or Magtech (at 150% to 250% the cost)? Or some generic small game JSP, that would at least be vaguelly the same bullet weight as the training ammo?
