After a two-month waiting period the antlers of the almost-600 kilogram moose that Heinz Naef shot in late September were given an antler score of 263 and one-eighth points.
The rating measures length, width and size of the antlers and palms and Naef's moose was one-and-a-half points higher than the old record set in 1994.
The waiting period was required for the antlers to dry and settle.
But Naef says the delay was worth while, given the record-breaking outcome.
The antlers will now be taken to Nevada for official verification by the Boone and Crockett hunting club.
