I live in Florida and shoot Snipe on the St. Johns River Marsh. A Snipe hunt is great exercise and a challenging shotgunning experience. I can offer a few tips for success if you can find a population of Snipe in your area. Try to walk into the wind. Use a short barrel and an open choke. I use a 24" barrel and a skeet choke, others use IC. Use small shot, I use #8 but some use larger.
Pick your shots. Snipe will get up from 10 yards to 90 yards as you approach and they can get up from anywhere in reference to your position. I like to take a shot at a Snipe that gets up at 15 yards, this gives me plenty of time. A shot at 20 yards is OK but you have to move faster. If they get up at 30 yards they do not get shot at unless I feel like I need to miss some more. Snipe, bless their hearts, will tell you when they have flushed. Listen for them to say Snipe, spin to the sound and try to pick them up in range.
You will miss a lot and this is the sport. They can fly 90 degrees away from their original path in a microsecond. Once you harvest one and prepare it for the table you will be suprised by its size and flavor. My wife and my Mom like them. Works for me.
One last tip and I am not being vulgar. Shoot him before he (censored word). After that he is going on some vector far from his original course.
I have missed them by 10 feet and more after they dump.
