Think you mean Hornady's Critical Duty line, which is barrier blind and intended for LE; Critical Defense is built for civilian defense and isn't a barrier resistant round.
Excellent choice on Speer GDSB -- one of the best out there.
I was indeed referring to Critical Defense. I base my statements on this test by DocGKR. The initial test was disappointing, but the subsequent one with a "revised" FTX demonstrated reliable expansion through 4LD. I opine that true "barrier blind" rounds aren't as critical for civilian SD scenarios as they are for LE ones, but are to be considered a bonus if and when they're available.
Also, thank you. I got tired of having to scrub lead from my Chief's bore and charge holes.

ETA: I wanted to make sure, but a quick glance at Hornady's LE website reveals that there is no 110 gr. FTX available in their Critical Duty line.
