Does the 100gr TTSX provide any advantages over the 80gr TTSX in a 257R for WT deer?. The reason for the question is that I have a finicky rifle and the 80 TTSX and 75gr Vmax seem to be the only bullets it will tolerate.

It would seem to me that the only difference in terminal performance between the 2 bullets would be increased penetration potential for the heavier bullet. But if the 80gr TTSX (3400ish MV) will pass through a WT from almost any angle, would the heavier bullet actually provide any real advantage? Thanks

PS I have no need or interest in shooting beyond 250-300 yards so the BC of the heavier bullet is of no consequence to me.
