You can’t go wrong with a Winchester model 88 in the old reliable 308 or 243. Fast handling and a joy to shoot. I have several in my collection and they get the job done.
My only caribou hunt in the late 90’s. It was the mulchatna herd and it’s almost unbelievable what happened to them. We literally saw thousands of them. Definitely a great hunt and I wish I could have gone back while the herd was still str.
