Speer TNT 125 grain Supersonic - Good hunting bullet?

[buffetdestroyer]

I saw that someone voted in rsilvers' poll for the Speer TNT hollowpoint 125.

I bought some of the Nosler 125's for supersonic shooting, but the Speers are about $12/100 cheaper if bought in bulk.

I am looking for something good on Mule/Whitetail sized game that won't over-penetrate and instantly knocks them down if hit in the vital zone.

Before dropping any more money on lots of bullets, I wanted to see what others' experiences were with the Speer TNT's.
