I look , pick something I haven`t killed with ,test zero , use it . Yesterday I shot one with 783 300 Win. 150gr Winchester deer season . Rifle shoots three into an inch at one hundred yds, lol , spike walked under me at 10 yds. Shot him through the neck came out shoulder . Always wondered what a magnum would do , now I know . Man what a mess . Next up is a 444 . Kenneth
