I have killed every moose I have killed with Winchester SuperX in 180 grain, 1 and done.
The only moose I put two rounds into was when I dropped a moose with a frontal shot as soon as he came up a valley @ 150'ish yards, I called him in.
He dropped immediately, I took the second shot only because I wanted to make sure he was dead because I did not want him to get up and head back down the valley, which would have created a lot of unnecessary work dragging him uphill, had he got up and headed back down the valley.
We got the side by side, drove up to him, quartered him loaded him, and back at camp before noon for beers followed by a tenderloin BBQ.
Best BBQed dinner I ever had in my life!
