What do you have so far? It is hard to help further if the basic nodes aren’t working without screen shots of your set up and a more detailed explanation of the effect you are achieving. I think I get the effect you WANT but I don’t know what the issue is or how to help because all you tell me is “it doesn’t qork”. What doesn’t work? What part specifically? The bullet flies in an arc but it’s the wrong arc? The bullet over or under shoots the target? Etc etc
