Depends on area I am hunting in. Heavy wooded area with shots under 75 yds-100yds. go a with .30-30 model 94 Winchester. Power lines or fields then would be Ruger m-77 in 30-06. Last couple seasons been taken the .50 cal muzzleloader for both. I dont think there is one caliber gun for deer. Everybody has they different thoughts on which gun is best for deer.
