I watched the movie "Shooter" last night for probably the 20th time. The makers of the movie went to great lengths to get a lot of gun details right. There's a lot they got wrong, though, especially for important points.
Bob Lee Swagger goes to see the old gunsmith to ask about paper patching, as he thinks it's possible the bad guys took the bullet he shot at the Dinty Moore stew can and used it to shoot the archbishop. The problem with that idea is that, even if the bullet went through the can fairly cleanly, it still wouldn't be useable, and certainly not usable for the 1800 yard shot.
Near the end of the movie, he presents his case to the attorney general, who releases him. Unless I missed something in US law, the attorney general cannot unilaterally dismiss someone charged with murder. Even if it's possible, does anyone think is likely?
He rescues FBI agent Nick Memphis by shooting the bad guys with a .22 rifle with a scope and a plastic bottle for a suppressor. Even forgiving the plastic bottle suppressor myth, the bottle would have obscured his view through the scope.
Also, near the beginning and the end of the movie are scenes where he's walking about 1/100th mile an hour. At that speed, wouldn't a person fall over?
