Re: If the stuff really hits the fan.
Most of the ammo i see in 7.62 x 39 is of the non reload type. Should shtf this ammo will dry up. Importation of this ammo will cease and probably long before shtf will happen. Domestic manufactures will not care about this ammo since they will probably be making 223 and 308's out the a$$. I think ammo is the biggest reason for your decission on what gun you may want to have. A gun without ammo is a paperweight.
I like the way some people think. I see it all the time. A guy buys a pistol at a cheaper price and says something like "well I bought this cheapie cause I am only going to carry it in the car". What this person is actually saying is that in the worst position I could possibly be in, I will accept a cheap POS to defend my life with. Think about it, does your life not deserve the best you can afford? Also does your life not deserve a weapon you will allways be able to find ammo for?
How much ammo is enough? When you think you have that one figured out, you dont.
Who are you going to serve today?
