One difference from personal experience is the lack of consistent performance from TSX’s on deer compared to TTSX’s which have produced completely consistent results.
The worst performance was a TSX in a .30-06 to shoot a buck in Saskatchewan. The TSX went through both shoulder blades without opening. Shot through both shoulders the deer ran about 150 yards. The buck was just shy of 300# on the scales. So there was plenty of body mass for it to open in addition to hitting bone.
TTSX’s have always opened with most falling where they stand. One time, shot placement was to the lungs just to see how the TTSX would perform not aiming for the CNS or shoulders. The .260 120 grain produced holes about the size of a quarter. The buck ran about 30 yards and did a face plant burying his antlers.
So, there is one difference from actual observation. Used the TSX on about 5 - 10 deer and no pigs. TTSX’s have been used on many times that number of animals - lots and lots of pigs, too many to count.
