Ten-fold!? In only 60 days!? WTF!?

I just got this broadcast email from the CMP:

AMMUNITION PURCHASE LIMIT: During the past 60 days we have experienced a ten-fold increase in orders for HXP .30-06 ammunition. This activity has significantly reduced our inventory. To ensure that the current inventory last another few years, effective immediately we are establishing an individual maximum purchase limit of ten cases of .30-06 HXP item # 407-Case and 10 cases of item # 415 per year.


Who is buying all that ammo, all of a sudden?
