You think this bullet will hold together better than the 250.
Please remember shooting into this medium is extremly tough on a bullet, much more so than the normal shooting of a big game animal, so I would say that shooting any of the FTX's would provide you with good results.
I would guess that 110 grains of BH would probably provide you right @ 1900 fps. And I totally agree about their accuracy - they are accurate...
