No, No, No........... I play video games a lot, like Battlefield 3, Arma II (dayz mod ^^
) They are no means a trainning tool, maybe to see realistic style of reloading but not to train to shoot. Thats why I go to the "gun range" on a monthly bases. That's one reason of a gun range to learn to shoot better. Video games are not ranges. You feel no recoil, you don't have deafening sounds nor do you smell gun powered when you play a video game.
Try a BB gun.
