At least two factors favor the 270 TSX over the 350 or, for that matter, the 300.
1. With monos, higher impact velocity promotes full expansion until the expansion cavity reaches its limit.
2. The expansion cavity of all three bullets is identical.
I have taken buffalo at ranges from 35 to 150 yards. The muzzles velocities have been 2750. As the ranges increase there is an obvious decrease in expansion. Sample size 11 buffaloes.
Have observed the same expansion/impact velocity relationship with 130 & 140 Barnes monos in my 270W.
This also may explain why the 300’s are more likely to fully penetrate buffalo; they don’t expand as widely which results in deeper penetration.
