I put a hole through a fallow heart last week just like that, it hadn't caught a rib on the way in so hadn't started to expand. Ammo was 168 hollow point
Yes, this was just one of those flukey shots too, it didn't touch anything solid! 30.06 with 165 grn. Nosler BTip at about 50 yds. I shot one last night with my 300WM using a 170grn SP, I could have put my arm through both entry and exit wounds!
