I am not an expert but I can tell you my son nicked a small apike with a bow several years ago. The deer ducked and turned and he just grased the fromt sholder due to a slow jr. bow shooting about 35 pound draw.....and some buck fever too I supose. he had blood and hair on only one fletch and I have tons of old film pics from the cam the next two seasons of that deer after the shot. His wound healed up in about two weeks but we only had night pics after the encounter.
I have no way of telling for sure but he killed an 8 point from the same stand comming from the same direction 2 years after that and that deer had the same exact scar. Again, I'm no expert but it's plain to me that it's the same deer. I could be wrong but this deer used a small tract of land (about 30 acres) and we watched him year after year. Hope this helps.
