I say try it. You could always bring some 300 gr bullets also to compare with. Even if the petals break off, that will not significantly reduce the weight of the bullet, merely reduce the frontal area to the same size as a solid.

I recovered one of my Barnes 235 XLC from an impala shot at 15 yards while shooting through a mopane tree top. (FYI - I was dispatching a wounded impala) This load was chronographed at 2900 fps. The nose expanded but lost the petals resulting in only a 10 gr weight loss.
