Because 10% is an industry standard that many States think is appropriate.
Also, Wyoming has never held NR's to even anything close to 10%, including LQ tags here.
Nobody bothers, in particular NR's with their hair on fire, to look at the actual number of licenses that NR's obtain in Wyoming. Its nowhere near 20% of deer or pronghorn, nowhere near 16% of elk either.
Plus, the deer tags are region wide, and those numbers are based on anything to do with a percentage and there are thousands of them for NR hunters.
If you want to hear some real NR crying, set strict limits on the 16% of elk and 20% of deer and pronghorn tags and not allow any more than that.
Fact is, NR's have had, and will continue to have it good even if 90-10 were to pass for all species.
There is a total misunderstanding of the generosity of WY in regard to NR hunters, its tough to find another state that gives access to tags like we do.
Show me another State that issues over half of their LQ pronghorn tags to NR's...for starters.
