Going around to gunshops earlier today ...
One shop I visited always has ammo ... LOTS of ammo .. and no buying limits. The only limit is the prices.
They had at least 100 cases of 1000 rounds each .. 9mm by ZQi Ammunition. Steel-cased I think. $1200.00 a case!
.22 Long Rifles for $17.99 a box of 50.
I have to stop going and looking.
