Last morning of the hunt. We came around a 90 degree bend in the river and she just emerged on the opposite bank. My guide eased the boat onto the gravel bar for me to shoot. The range finder said 310 yds. I squeezed one off and hit her quartering away. Guide said shoot again. We heard that one hit also. Cow started for the timber and I sent another to her boiler room. The final shot changed her mind and she turned for the river, went 20 yds and collapsed. I used my 1965 Winchester Model 70 in 7mm REM Mag. 61 grains IMR 4350, MV 2840 FPS, 165 grain Norma Bondstrike. Upon opening the body cavity, all three bonded bullets struck behind the shoulder within a 5 inch group. Amazing how resilient these animals are. My first ever moose hunt
