When I was a wee pup my Dad went with a couple buddies went 100 miles and bought I think 50 bags once . Seems like it was 10-15 bags each . Extra hard and chilled shot , #4,5,6,7-1/2,&9 . I recall Mom being upset about $55 , because they took Dad's truck and had agreed to buy his gas and lunch . Dad bought the extra bags because after they got there the guy knocked 50¢ a bag off and paid the sales tax if they bought 50 bags . It was probably an inventory tax sale or the like , in any case circa 1970 Cali $5.50 a bag . In 76-77' he bought #2,5,6&7-1/2 out of Carson City that was Extreme last I saw and made dropped shot those were only $8/bag . About 2000 I guess it made a big jump from $12 to 22ish . I almost choked on the first I saw at 42-48 that wasn't even plated shot , 2013-14'. It was cheaper to buy loaded ammo than parts to load it .
