Part of it may simply be that supply caught up with civilian demand that went through the roof when would-be gun grabbing politicians made high-profiles pushes for tighter gun and ammo controls in late 2012 and into 2013.
On the other hand, sluggish international economies may also be contributing to present supply.
At SG Ammo, I noticed this as part of a description for a batch of M855 ammo listed on its site:
Original consignee was the government / military of Saudi Arabia, this is your chance to take advantage of the bust in oil prices to get real mil-spec Lake City M855 ammo in military packaging from a canceled military contract.Take it as a sign of dire times if a country in the Middle East lets an ammo contract lapse to save a few bucks. Especially a country like Saudi with ISIS pressuring its northern border, and Iranian-backed Houthis to the south.
I wonder if governments elsewhere are also backing off on ammo purchases, freeing up more production to focus on civilian markets.
Regardless, present prices and availability may signal a last call for those American gun owners who haven't sufficiently provisioned for what comes after presently stressed economies take a more obvious downward turn.
American civilian market ammo inventories became seriously stressed after the past two U.S. presidential election cycles.
Now may be the time to assess both your immediate and long term needs, and acquire accordingly.
