I haven't time to check and see if this was posted - so sorry if it should be a repeat.
gun-deals.com - Unbiased Gun Deals - represents a source of current deals but wow! Prices have gone crazy.
Cheapest 7.62x39 seems to be $280 for a case, when way back at a gun show I got that for $80 - out the door!! Crazy.
Must prove a point huh?!!!
