Actually I have to disagree with you Freycinet. Talking about limitations from your part, or angle of attack from Martin is irrelevant. Wood or canavas does not leave perfecty drawn circles when hit by a bullet. This is not a compromise or so, with all due respect, its simply bad. Just check any random damage skin made for FB so far and you will see what Im talking about. Metal is more likely having a roundy (but not a perfect circle for Christ sake ) hit mark, wood and canavas wont. Not to mention they made the bulletholes a bit bumping outwards, which makes it look like some chunk of butter been shot.
You can also check any random first person shooter. Go and have a shot into a wooden door. It will be far, far from a circle. Or just go shot a piece of wood yourself, you will see
