I've used an Uncle Bud's Bulls Bag for years.  Just fill it with sand and your ready.  I've shot many a one inch group @ 300 yards with this set-up.  Costs around $60, but I believe it's called something else now.  It's just looks like one large sandbag with four seperate sections attached.  The gun lays on top between the two smaller sections......very steady.
