Yes Sir the 100TSX will penetrate a buck's shoulder, & a good buck at that!
I use a 115TSX in my Sendero, only because it grouped much better in
that gun than the 100. I have shot Ar. Whitetails, Mule Deer & Antelope with this small caliber "Hammer Of Thor". I have yet to recover a bullet, no matter the angle or distance! Once I had a Whitetail Buck come under
my stand quartering toward me. With the quartering & downward angle, I
shot in in the point of his shoulder. The bullet busted his left shoulder, angled in a straight line down & back through a lung,liver, dia. guts, exited just in front of where the rear leg would normally be, but he was stepping forward with his right rear leg, so it busted his leg bone just below the ham & went deep into the ground! He expired right then. This
was at about 15 Yards with a muzzle vel. of 3,250. And yet they expand
well at moderately long range, (350-400 Yards).
My brother's Sendero groups the 100 Grain, so he uses it. Again, he has
yet to recover a bullet! Use the one that performs in your rifle, & up to
Mule Deer size, don't worry about penetration.
LAWDOG CAN CERTAINLY ADD TO THIS TSX DISCUSSION!!!
Concerning the original question in this post, the ballistic coefficient is too
low (.250 at 2,800FPS ) for the Sierra 90 Gr.HPBT.
For Deer size game, the 100TSX BC is .420 , the Nosler 100 Part. is .377,
100 Gr. Bal. Tip is .393
For Varmits the 85 Gr. BT is .331 & the 75 Gr. VMax is .290
