Oldelkhunter-I have taken many deer with the 257wby and switched to the 7mmstw as an all around cartridge that would be more suitable for elk and moose as well.Since then I have changed to the 300ultra for elk and moose and the 7mmstw is now used for deer,sheep and pronghorn.The stw's shoot so well for me that I will not part with them even though they may be overkill for deer.
