I thought I would post a follow-up in case anyone was following or finds this thread later.
My son ended up taking a doe with a single shot, perfect placement. The doe tipped over where she stood, bullet passed through with a 2" exit in the ribs. Lungs mostly jelly, top of the heart was ripped apart. Overall, seemed like a very effective bullet although only one data point.
We'll likely use them again this fall.
