Don't claim to be an expert, but...
If you were to bring this up in the Big Game Reloading subforum rather than here in the nut house, you'd find that many of us regularly use 7mm-08 data as a guide for modern 7x57's. Alliant indicates 44 gr of RL17 for 2669 fps so you are pushing it beyond wisdom, you really should tone it down or switch powders.
But it is anything but weak, your acquaintance knows less than he thinks.
