Much derided by the lamestream gun media, yet it just won't go away. Why? Could it be the attempt by Winchester in introducing the 3" magnum 20 gauge ~60 years ago was a marketing effort to give a gauge relevance as it was clearly subordinate to the 16 gauge in the field? Reminds me of the rationale for the 12 gauge in 3 1/2" chambering in the early days of steel cartridges especially as the 10 gauge was making inroads into duck blinds as many waterfowlers were discovering it's superiority over the 3" loads in 12 gauge. So, what's the 16 gauge all about? It possesses the carrying characteristics of a 20 gauge get out patterns it (as the 10 gauge does the 12 gauge) due to the larger bore size. Also, it will hold service with the 12 gauge as a bird killing machine in the blind. The fear of 20 gauge proponents is their flock will try a 16 gauge in the field and then realize firsthand their victimization by the Church of 20 Gaugeology. All I will say is if you haven't tried one you are missing out on a well-rounded wing-shooting educational experience. Don't buy into the propaganda apparatus until you have experienced the 16 gauge for yourself. For the duckblind, I would suggest a MOD choke and Remington's Nitro Steel in #4's. You will not be disappointed .
