MGM, if you can locate them, try Rottweil or Brenneke slugs in your 16. They are far more accurate than any of the FedRemWin brands and as a bonus, they are a full 1-ounce where the FedRemWin offerings are 7/8 ounce. The Rottweil and especially the Brenneke are cast with helical driving bands that provide the accuracy. You can get both the loaded ammunition and the slugs by themselves if you reload as I do. I use them in both a FN Browning A-5 and in any of my 16 gauge Remington 1100s. It is a pity that FedRemWin can't or won't make a decent slug round for the 16.
