while tring to find bulk 5.56 at the gun show i was told our government banned imports of all millitary surplus ammo about 2 months ago. is there any truth to this?

i left the show with no ammo as no one had any for sale. are the working on banning all military ammo?

if this is true what was banned and what is still comming in? did they ban 7.62x34, 308, 7.62x54? what about 5.45?

the guy said Wolf was still ok because its not considered surplus but i don't want to shoot that junk as i already have had a stuck case with it.
