Sure, everyone is entitled to an opinion, & no ones' is more valuable than another. When we are discussing bullet testing & how velocity influences bullets, it becomes a tad " weird" to me that fenced vs non fenced comes into play. When it comes to large game & shooting them, I really don't think that the muscle mass & bone density of a Bison on a preserve or ranch to one that lives in Yellowstone National Park really will change bullet upset or penetration. I just don't see the relevance.
