I just ordered ten flats (gulp!) of the Federal N11975 - 24 gram 7 1/2 paper shells for next season.  With shipping, it's going to come to almost exactly $1,000.00US.  There is - currently - no rebate program on these so I'm spending a lot for these shells.  I do believe that they are the best shells money can buy, but $10/box...that hurts.  But, I figure that the price isn't going to come down, and neither will the shipping, so I may as well get them now while I can find them.  I hope this causes me to improve my first barrel percentage. ;)
