Very interesting.
But, as bone strikes, and running into bigger game than deer (even when targeting deer) can happen quite frequently - this gives a reason why I prefer using Barnes products. They punch through long tracks of tissue and go through bone more reliably than anything else I have ever used.
But, I'll be the first to admit that on perfect shots (no bone) on animals that are only deer sized - homogeneous bullets might not drop the animals quite as quickly as the lead-filled fast-expanders.
