I think that optimal penetration is suppose to be 12"-16". These loads went slightly over that, which is unnecessary. The penetration itself is not bad, but it's just not needed......and the bullet accomplished that penetration by trading for a smaller expanded diameter.
So, a more optimal bullet would be expanding slightly bigger while still penetrating anywhere between 12"-16".
That's my take on it. I think the difference is quite small in the grand scheme of things, and although not optimal I don't think the load presents a liability such as something like a 115 Silvertip.
