Wouldn't recommend it for accuracy, good story line or anything else other than to fill some time, however;
The league of Extraordinary Gentlemen has a fun scene with allan quatermain using his double rifle "Matilda"
An assassin sent to kill Alan is making a run for it, Alan asks the barkeep for matilda, who passes Alan a double rifle. Alan gets to the door of the club and draws a bead on the assassin, he then lowers the rifle and the guy next to him says something like he thought it was too far, Alan proceeds to calmly put on his glasses aim and fire at the guy now a couple hundred yards away, wounding him so they can question him, claiming he wasn't aiming to kill.
Don't know if its a recommendation as i say its not realistic such is the nature of an action film, the movie is not even that great, but its a fun gun scene.
The shooting party, and also gosford park both have some shooting in. Ken loach's The Game keeper is good and about the life of a keeper in the 60- 70's? not a lot of shooting but might be of interest.
