Here's something to think about.
I've bought pallets worth of ammo from SGAMMO over the years.
They always kill you on shipping, say if you want to try a couple of boxes of different types of ammo until you find what you like.
I went to Target Sports a few months ago and signed up for their Prime membership.
It's paid for itself in a month.
My first order was a bunch of Federal 5.56,not 223 @ $225 a thousand.
Next up some CCI @ $0.03 a round.
Right now they have 308 Remington match ammo @ $0.38 a round.
All their ammo is at damn near wholesale prices and free shipping whether it's one box or a pallet.
They also send you gifts of ammo that coincides with your purchases,that alone was almost worth the $99 yearly fee.
Just something to think about.
