re: Waterfowl hunting in NWR

i've read a shite-ton of NWR pamphlets, and never saw a shell limit anywhere. Limit was just how heavy my load of waders, guns, dekes and shells was going to be on the two mile hike back to the brake we would be hunting. At the end of the hike, we'd sit on a log and put on the waders, then walk out into the brake and toss out the dekes. Big fat mallards would make the load going back in heavier than going out.
