Instead of buying a 20 gauge Model 12 whose price was in the stratosphere of course, I decided to convert my 16 gauge Nitro Special that weighs 6 pounds 3 ounces, NICE!!!!!, into a 20 gauge with a set of Gaugemates.

Has anyone used these for hunting, upland, or waterfowl? And if you have, are they easy to use in the field? I bought one set should I buy another in case I lose, you never know and there is always Murphy's law, these while hunting?

Another reason is I'm planning to go to Africa for birds and I know if I plan ahead the PH can get some 16 gauge but if he cant I can always just use my Gaugemates and shoot 20 gauge ammo that the PH always has.

Is this a good plan?
