That is how TSXs work! lots of damage when the petals break off and the rest punches through and gives you two holes and NEVER any bullet failure. I was a big A Frame user and went to the TSX for that exact reason. Pretty mushrooms but the penetration just wasn't there.
That's why I went to North Fork soft points. With the same 300 grain NF bullets, I shot an Impala stem to stern (bullet under the skin of the ham) and hit a Cape buffalo in the spine/shoulder junction. DRT on the Impala. The buff fell down and didn't move a step. Both bullets, when recovered, weighed over 290 grains and you can't tell the difference between them.
