I am looking to hoard a few thousand rounds of AK ammo. This will be in 7.62x39. Thought of switching to 5.45, but don't want to have to buy 2 new rifles just to save a couple dollars. Figure I will aim for about 5000 rounds. I am not sure if one type would be better for storage over another. I noticed that there is polymer and lacquer coatings. Would on be desirable over the other?
My first thought is to go with whatever is cheapest, but perhaps one brand is better than another.
Really looking to find out:
Polymer or Lacquer?
Surplus Corrosive or Non Corrosive?
And Particular Brand or Just buy the best deal?
Any insight is appreciated.
