Several years ago, I got some "Gauge Mates" for the 16 Gauge Smith, this is when I realized the chamber was 2 9/16". 20, 28, .410 would not chamber in the Elsie without my chucking them in the lathe and trimming them a bit. They worked quite well and were used hundreds of times. The L.C. has ejectors and I had to be careful when opening the gun so's not to send everything flying. I use this gun mostly for skeet and an occasional walk in the woods. My main concern is the ejectors and the damage the "Gauge Mates" might cause with their extra weight. Course you'll all know how tough it is to use gauge adaptors shooting skeet and having to pick out the empties while others are waiting.
Thanks for taking the time to read this. Jay
