If you have £30, buy yourself a lovely 'Camo' shooting bag.

On the other hand, if you have a small backpack/daysack that you dont use, go to the Habidashers (sells buttons, zips etc) and get a large sack of polystyrene beans, £4.

Fill bag to required size and 'hey presto' you have a shooting bag that suits your needs, has sholder straps and cost about £2. There's lots left over, I have a 'bean bag' bench for cleaning and holding my air rifle, made out of an old nylon 'sausage' hold all. Plus you will have a bucket or so left for nicley packing the many items you will trade on the BBS.
