USAammo operational????

I am not holding my breath nor risking USA AMMO holding onto my $$ and not filling orders in a reasonable amount of time. 30 days after they get the $$ I didn't have the ammo and they never answered a email.It took 8 days of calling before someone answered the phone and I had my money refunded.There are too many reliable sources for my ammo needs out there and I will happily pay more if I don't have to waste stomach acid worrying if my order will get here.

They don't make anything special enough to risk having your gun kaboom. I won't be using them.
