For sheep and alpine blacktail I used a Fieldcraft 7/08 last year and I'll do the same again this season. Prior to that a couple different Montanas and for years before that a 270Win 700 dropped in an Edge for my backpack hunts. Still have a 30/06 Montana and the 270 squrirreled away but that Fieldcraft sure is light and compact which matters to a lot to me when you carry it for days and miles to only shoot once.
