If I am reading right, the deer went 60 yds and piled up.
Thats about typical if there wasnt a CNS hit. Ive blood trailed more than a few hit with buckshot and the trials are usually not as heavy as you get with a centerfire. I always figured that was due to round pellets that dont expand and arent moving very fast , compared to a rifle cartridge. IF the shooter did their part, there was usually a dead deer at the end of those blood trails. When their wasn't, shooter error was most often the culprit.
