Both the TSX's and Hornady Interlocks tend to produce less pressure than most other bullets, but how much compared to each other depends on the specific bullet weight. The lighter-for-diameter TSX's, with fewer "bands," result in less pressure than others.
You can probably get those two bullets to shoot to the same velocity by tweaking the charge with the Interlock, but whether they'll shoot to the same place is another question.
I have one rifle, a .257 Roberts, where 100-grain Tipped TSX's and 100-grain Ballistic Tips shoot to the same place with the same powder charge. You just never know until you try.
