...Is a 90-100g TSX really as effective as a 123-125g SST/Partition on whitetails (let's assume Midwestern deer - 175-250 lbs)?

Their performance in wet paper and gelatin suggests that the equivalence is correct between the 90-100gr all-copper expanding bullet and the 123-125 grain partition.

We would be looking at more like a 150 grain SST to get the same equivalence to the 90-100 gr all-copper bullet.
