"Is the 7x57 mouser the campfire cartridge of 2016?" No,it's the .270 the "happy" cartridge everyone should own.
Elkhunternm,
Last year I acquired a Sako Finnbear L61 in 270. It has a nice wood stock and shoots 150 partitions into little tiny groups. It certainly made me rather happy.
In the works for this year is a 7X57 and a 6.5X55 Swede. I've got a 7X57 barrel on the way and a Whitworth action to go with it. Rifle should be completed in a few months. I have no idea what route I'm going to go concerning a Swede but there will be one in my gun cabinet sometime this year.
