Bullseye,
The powerbelts I was using didn't have the plastic pointed tip just the hollowpoint. The buck I shot using the 225 pb hit backbone, knocked him down, but he got backup and I had to shoot him again in shoulder even closer, that put him down for good and insides looked like a 30-06 hit him,but it didn't exit. The other three deer were does hit in the ribs. Only one had a complete pass through and a impressive blood trail although she didn't go but about 15yds. The other two does only went about 15-20yds also, but no blood trail and no pass through. I recovered a couple of the bullets and they flattened out like a quarter.
Maybe the powertip powerbelts do better as they are designed for better penetration. I want to try the flat point powerbelts that they have now, but haven't seen any locally yet. They are only in 444 grain also in .50 cal. that should punch through about any animal in the woods.
