Body Size
Weights are frequently used to describe large animals. They are usually qualified with a statement
that the weight was: live, whole, hog dressed, skinned, or with the head off. Also, weights may be
determined by a guess, experienced estimate, or a scale.
Several variables are known to influence skeletal development and consequently affect the skull
size, tusks, muscle tissue, fat deposits, gross size of the animal, annual replacement of antlers,
and increments of horns. Extremely large antlers or horns do not necessarily correspond with an
exceptionally large body size. If the antler development is not outstanding, the body condition
or size is a preferred description.
This section provides a listing of some of the largest weights on record for the various Montana
big game species. As such, the standards require verification and the use of a certified scale. Whole
weight is either from a live animal or a dead and uncut animal; dressed weight is an animal with head,
skin and feet attached and the complete viscera removed.
Future records should include sex, date killed, location taken, hunter name, and observer names
for the scale weight.
