The fields around me are like swamps. I'm also shooting hundreds of rabbits a night at times on foot, no way would I be laying down in a bog every time getting wet just so I can shoot prone. I'm taking rabbits out at 150yds with an airgun just fine off quad sticks, so I'll give the lying on a waterlogged floor a miss and it will save me buying a wetsuit as well... I've been shooting a pretty long time to know what works the best ...If you want maximum precision and repeatability, that's the way to go. Getting wet is no big deal. As far as foliage, there is a distinct advantage in shooting from standing. It comes at a price though. If it is convenient for you it depends on what you want to accomplish, on your expectation and on the kind of enviroment you are hunting in. For me going prone when shooting past 150/200 meters is always doable. It just comes to finding a decent position, which is almost always doable. At that distance you have usally some margin to move and find a good prone position.
At least in my experience
