ok guys i'm going to wyoming again this fall and looking for a deer rifle that will put him down in one shot. I brought my 7mm out there two years ago and hit one in the shoulder and he didnt go down. i wasnt aiming there but thats where it wanted to go.. where we are hunting the longest shot is maybe 150 yards.. any suggestions and what type of bullets to go with it to nock one of these muleys down? thanks
