I started shooting moose with a Winchester Model 670A in 3006 and Federal blue box 180's. Worked fine critters died. Then I built a 338wm about 6 years ago and that's been killing them since then.
I'm a freezer hunter so most of mine have been spike bulls although one of these days I'm going to go after a big one.
This is the first one I nailed with my 338wm. The weather had just turned two days before from kind of too warm to downright nippy and the game started moving.
The falls near camp.
Then the snow came.
Then critters started moving.
