RE: which Calibre
Since you,ve been shooting a 22 250 I recomend the in no order 260rem 7mm08 308win 338 federal 6.5x55. Its simple you already have and shoot a rifle in a short action you presumably shoot well. Get another 1 in the larger caliber. A million moose have fallen to the 6.5x55 in Europe ought to be enough elk here.
