Alberta, I think you are right.

Lead shards travel quite some distance from the main axis of bullet wound channel, and if the bullet is long-for-caliber, the bullet will still travel deeply...as long as it doesn't totally break up.

In my testing this can be seen dramatically, where shards will create a "shotgun" pattern effect surrounding the main wound channel {picture a bullet hole surrounded by a shotgun pattern}, and this can be seen plainly in the plastic jug walls. It is quite interesting to note. Obviously, monometal expanding bullet do not do this.

Now, as for whether this 293 TUG is long enough for caliber.

Does a duck quack?
