In order, my preferences would be .300 H&H, .30-338, and .308 Norma. Your mileage may vary.

I have a 24 inch Krieger barrel 30 Caliber with 1-10 twist. Currently chambered for .308. New to rechamber. I have a .308 and a .300 Win Mag. Any suggestions?

30/338? derf

How about a .300 WSM or .30-284?

Always liked the 308 Norma

You already have a 308 and 300 Win Mag. If it were me, I'd sell that barrel and buy a different bore size. Shouldn't be too hard to get rid of, and you could probably use a big bore up there in Cold Country.
