I know that caliber choice is going to invoke many opinions but that is basically what I am looking for, a second opnion. I have shot a 22-250 for years and love the round but in the past 2 years I have not been able to find factory loaded ammo (other than varmint rounds). So I am looking for a new caliber for long range hunting, but my question is what would be a round that will be fairly easy to aquire factory loads for long term? I was orginally thinking of the NATO 7.62 X 51 because even if the anti-gun government radicals restrict other rounds NATO could still be aquired. Suggestions???
