I have a 35 Whelen loaded with a 200gr barnes TTSX at 2900fps. The factory Remington 1:16" twist limits this round to about 250grs. Thus the 9.3's start basically where the 35's stop with some overlap at around 250grs. It's an interesting comparison between a 375 Raptor and a 35 Whelen, but they're very different cartridges. The 375 Raptor reminds me of a scaled up 35 Remington and loaded to modern pressures, which is a very good idea. I think a 375 Raptor in a Remington760 would be another great idea.
