Why would you need that heavy a bullet for deer in the 7 mag?
My thoughts also. I've never understood the logic behind buying a fast stepping round like the 7mm rem mag then loading so heavy a bullet that it brings it down to 7mm-08 speeds. Pick a good 140 grain bullet and load them to 3200-3250 fps then go shoot some deer. Any good 140 gr bullet will penetrate far in excess of anything required for deer.
Now on the other hand, if someone gave you a bunch of 175 gr core lokts and you just wanted to get rid of them then sure, shoot them at deer. They wouldn't be anywhere near my top choice for deer out of a 7mm mag unless that was the only thing the rifle would shoot well, then I'd probably rebarrel the rifle instead of being stuck shooting that bullet for deer.
