What do you think he damage from an M14 if a person was hit in the shoulder from the front would look like? I’m trying to make the damage from the hit as realistic as I can! [if distance is needed, it is about 4 to 5 rooftops away. tight old city blocks rather than larger apart] Thanks for the advice!
No offense, I don’t particularly want to look this one up, but wound channel charts are available for most common rounds. It’s a little harder to find ballistic data for unusual rounds, like 5.7mm, but the M14 is chambered in 7.62mm NATO. It’s a very common round.
Off the top of my head, you’re looking at a fairly small entry wound. The exit wound will depend on if the bullet hit bone on the way through or not. If it did, it it will shatter the bone, and take that with it, leaving a sizable hole on the way out. (I’m going to spitball that at around 2″-3″), if it goes through clean, which is kinda unlikely, but not impossible, you’re looking at an exit wound not much larger than the bullet.
It’s also possible, on a bone impact, for the bullet to shatter resulting in multiple exit wounds.
Generally speaking, when you have deeper penetration of meat with a 7.62, it will start to expand. Someplace after about 10-15cm of penetration, it will actually produce a much larger tissue displacement. This isn’t really an issue if you’re pumping rounds into a person, but if it’s something larger, or if the bullets are hitting center mass, it can be a factor.
