I don't know of a link but this is exactly the note Greg put in his ammo price list.

Note due to the recent events:
1. Import ban on surplus ammunition.
2. Talon MFG shut down.
3. Continued component price increases.
Above prices may not be valid in April and May. Call and order EARLY.
The dems are in power and this is what happens. I don't know how it happend as I never heard anything about it until I seen Gregs price lists.
