If you get onre that wfasn't subject to the dremel tool regulation they are decent. If it doesn't shoot to regulation then Cabellas has a 30 day return policy.
IIRC the Safari are a little fancier lazer engraved and probably has ejectors.
Get a 450 NE and not the 470. You're already set up for loading it. The 470 doesn't do anything the 450 can't. They're pretty close to being twins.The 470 is sixteen thousandths bigger and tosses a 500 grn slug at the same speed as the 480 grn the 450 uses. I shoot 500's out of my 450's with no change in the regulation.
