Nice job. The 250gr TTSX is the bullet I've been wanting to try in my .375 Ruger as well, as the 260 Accubond didn't penetrate like I wanted. Looks like this one will. My moose season opens Saturday, so I hope my luck is as good as yours.
I used the 250gr TTSX in my .375 HH. A couple years ago I called in a 54" bull and shot him straight on at about 45ish yds. The bullet entered his chest and exited out behind his last rib.
I think I am going to use that set-up again next season.
