I went back and read your original post again. That BDL you have should be a good gun. Be a pretty easy semi custom to make if you wanted also. I guess the things I like about the 7RM and I will even throw int he 300WM in this group as they are closely related although some differences. They are fairly cost efficient to shoot, meaning brass is not as much as the big magnums, it doesn't take as much powder. Also, for what it's worth, I am able to take those long ole 180 Hybrids and seat them .01 off my lands and still fit them in the magazine.
With all that said, that 300WSM is a good gun too. hahahaha
