Recovering only one out of seven means you hit some nice bone with the one you recovered. I question whether the Aerotip ones that exited expanded any. Most reviews I've read state the same-sized hole exiting as going in. That particular copper clad tip was designed for game larger, tougher-skinned than deer.... ie... SSTs. At normal 100 gr ML speeds, copper hollow-points are tough to beat for deer. You can pay more for that pretty tip/pretty look, that's OK by me.
