Steadying your in-game weapon by pulling the butt of the rifle works as promised, as does zooming in or looking through the scope by leaning your head toward the rifle's stock.
Sighting in a target through the scope of a high-caliber rifle can be a bit more complicated than it sounds -- snipers have to account for cross-winds, range and a whole host of external factors that could put their projectile off course.
Yet, when the hundreds of hours of legislative debate, on camera pleas, backroom negotiations and intense lobbying have ended, groups like the National Rifle Association may find that they have narrowed the scope of gun control legislation.
