yeah a 7MM will definatly do the job, a buddy of mine uses his for moose and has great success with is and a deer isnt nearly as big, so i say go for it. like maine shooter says dont listen to everyone on here, and put it this way, all the magnums are starting to become popular nowadays, but what did they use in the good ol days? the magnums arnt really necessary, i use a 30-06 for everything and it aint no magnum.
