There was a picture in the local Fish/Hunt related paper up here that showed to women (and their female guide) that took a nice bull moose with a .270. Not too sure of the range, but up here Moose shots tend not to be too far. Keep the ranges reasonable and you should be OK. Heck, me personally I would be wary of even the 06. But of course that should do the job too. Im thinking of having a custom .350 Mag barrel made for the off chance I someday get my ticket pulled for the lottery up here.
Good day,
Brian
