Sweden

Saw a movie in the late 90's or in the early 2000's. An adventure about an elder man and a kid (maybe two kids) that finds or are in possession of something - a book or medallion or something that made things from the past appear in their time. I remember lions and a hunter chasing them with bad intents. A lot of other things chased them as well, but I remembered those things specifically. I only remember one particular scene which involves the hunter entering a weapons shop trying to buy ammunition for his old rifle, and the clerk clarifies that the round the hunter displays has not been for sale in a long time.
