I have a Canuck defender with a 28" barrel and I have only shot 2 3/4" shells through it without a problem. I am going duck hunting for the first time and the shells I have are 3". Can I assume they will be just as reliable or do I need to go test them out. The range I go to is an hour away and I'd also need to find time. I'm sure with a Remington it would be fine I am just asking because the Canuck is a cheap gun. Thanks for your time, any response is appreciated!
