Every 15-20 years someone declares the 16 ga has risen from the dead. Funny thing is, you never hear that it died in the first place.

I have about ten 16's, heaviest is an NID that I can use for ducks if I like, lightest is a 2-1/2" Kettener at 5-8. I can get 2-3/4 loads at Walmart, the lighter stuff must be ordered from RST.
