I had the Marlin Super Goose in 10 gauge. I remember a 34" barrel, someone had opened up to modified choke. I've never had a worse shotgun. Handling, just imagine holding a 2x4. Fit, they had a barrel band to kinda, sorta get your eye in line, but was no substitute for a proper stock. It never patterned worth squat. The only acceptable steel shot load I ever found was the Remington 1 3/4 ounce (not a typo) T shot. That was a solid 45-50 yard goose load from the gun, but I only found that one box, and never saw that for sale again. Sure enough, the ultra expensive Hevishot HeviSteel in BB worked just about as good as the Remington load. Any other load, and a 35 yard shot was iffy at best. At something like 9 1/2 pounds, it is way too light for a 10 gauge as well. Recoil is just like a 3 1/2" 12 gauge. If you want a handier 10 gauge, get the Browning BPS pump. If you want a true long range waterfowl gun that you can shoot without flinching, get one of the three semi autos.
And the big bummer was the reliability. It was an acceptable single shot. The second shot you had a 50-50 chance of it working. There wasn't much point in trying for the third. The last day I had it, I was out and had two geese get scared up by a swan on the other side. They came right over me, a perfect 20 yard crossing shot. First shot, folded the goose up solid. Went for the second goose, and click, CLANG! The magazine had fallen out and hit the bottom of the boat. If it were not for a goose feet up, I would have bent the barrel over my knee.
The very next day I traded it for a MAC automotive scan tool, and never looked back.
