Almost 100% of the time. Not many airlines are keen on flying ammo around.

I'm a sample of 1 so take this from whence it comes and with as much salt as you prefer.
In 30+ years of shooting I've only ever bought two rounds of factory new ammo that were visibly defective. One was a 9mmP and one a 270 Win. Both were from PMP and both were deformed such that they couldn't chamber.
So bought some Winchester 9mm Luger 115 Grain FMJ 100 round value packs but they don't have a headstamp like WIN or the like.
It has 3 things, "WMA" which I thought was WIN at first and then the number "20" and then a little symbol which looks like a circle with a line going diagonally and one vertically through the middle of the circle. Anyone have any idea what this is, is it because it is a value pack and cheaper. Would the quality of the ammo also be poorer if this is the case?
Nothing here https://www.cartridgecollectors.org/...adstampcodes#W
WMA headstamp I believe is "Winchester Military Ammunition". The cases sometimes get used in their commercial offerings so not necessarily indicative of military ammo.
In America (don't know about here), the cheap Winchester range ammo is known as Winchester White Box. They seem to sometimes use the WMA (I understand, previously WCC) headstamp cases.
Military ammo is normally loaded using Berdan primers, the case does not have a central flash hole, but rather two smaller off-center holes. The primer is crimped in place to prevent it from coming out in automatic weapons and causing a jam. The primer is not "self contained" like a Boxer primer (containing an anvil in the primer), but the case has the anvil as part of the doppie.
Military ammo is normally also slightly "hotter" loads, as far as I know.
Great thanks learned something new today. I always thought that Berdan primers were mainly used by the likes of China and Russia never knew the West used Berdans. Is it something to do with the military not wanting them to be used for reloading by potentially the enemy during war time or what?
