I don't believe BBore's biggest will chamber in the Smith, but the 305 grain hardcasts should. Garrett's 310 hardcasts are also approved, but not their +P stuff.
A word of warning. Do not come to Anchorage, let alone Bethel, expecting to find a good supply of this or any other ammunition! We've had terrible shortages particularly during the hunting season. Bring what you need with you.
