Montana's bighorn sheep are a magnificent animal and a symbol of the west. If you have obtained a ram permit, legal ram’s horns must have a three quarter curl. If you draw a straight line from the front base of the horn, which is where the hairline meets the horn, through any portion of the eye and it intersects with any portion of the horn, you have a legal ram. Whether you have a ewe permit or ram, Montana's bighorn sheep are a symbol of Montana's outdoor prowess and strength. Good luck and happy hunting.
