In this Outdoor Recreation video tutorial Dave from 'journey the outdoors' explains how to make a bench shooting bag. This is used by bench or week-end shooters for recreation purposes. For this you will need an old sock. Take one that you don't use anymore and preferably a tight knit sock. Then fill it with rice and tie the open end of the sock. You can also fill it with beans or some other such substance. Rice and beans being bigger than sand, there will be more air in the bag and it will also be lighter. You can then give a dent in the middle of the bag with your hand for the arm to rest while shooting.
