The shock waves look alot like the hornady sst-ml bullets and as I just posted I hit a doe about 65 -75 yards away with 100 grains of pyro pellets and a 250 grain bullet. It went straight through the rib cage and made a hole about the size of a fifty cent piece gone in and slightly bigger exit hole. This tells me it expanded and stayed together.
They are the same bullet actually, all manufactured by Hornaday but as SW by T/C with a different colored tip.
