Jaybe---The reason they have to put "Tentative" is because everything is finalized by the Wyoming Game Commission, which usually happens in late April and then that is actually put in print and on the website. Until that time they are strictly what the G&F people want to see take effect for the coming season. Antlered isn't like what you mentioned here in Michigan (I'm in Allegan). To find their definition you have to go into Chapter 2 of the Hunting Regulations and look at Sec. 2(a) which states "Antlered" means a deer, elk, or moose that has visible antler growth plainly protruding from the skull. Where a minimum number of antlered points are specified, points shall be counted on the side with the greater number of points.
Since there is nothing to exclude browpoints in that definition, my feeling is that they would be counted and since the initial definition says what "antlered" means, I would think they would be hard pressed to say that a point would have to be any longer that what you could see coming off a beam.
