If the US banks start defaulting on the 250T of open derivatives, then you might just want to keep them all and put 28 rounds in each, stick them in cans, and then top off as required.
It appears that APEX has quite a few VZ58 mags available. I used to sell from my stash if I rented a table at a show, but the prices are now below what I paid for mine 4 years ago.
Same for Yugo BHO and Bakelite AK-47 mags and drums. I can remember when people bought Bakelite mags for $80 and Romanian drums for over $100 -- now they are under 40 and 70 respectively. Now may be good time to stock up if you have the budget.
I wish Fahal would drop the price on the VZ58 drums down from $200.
