I think I know a little myrtle-stocked mauser going on a boat ride in the AM just hoping it gets pointed at a moose by a certain 15-year-old with a hot tag with a start date of yesterday...

Same 7x57 got pointed at a black bear last fall and the bear died... Thinking a moose might have very similar odds.

As to options considered prior to the selection of the 7x57: 243 (several), 6mm, 25-06 (several), 7-08, 30-06 (a half dozen), 308Norma, 300H&H, 300WM (several), 8x57JR, 35WhelenAI, 375AI and more...

The 7x57 will do just fine I am certain...
