"Have you been involved with changing your states air gun hunting laws?" Yes. In fact inadvertently; but perhaps the first to do so in Texas.
In my first airgun book titled
The Manic Compressive (copyright 1998) I criticized (among others) Crosman for their classic-to-plastic devolution, Dr. Robert Beeman for his shameless-profiteer bad-mouthing of American multi-pumps and .22 caliber, and Texas Parks & Wildlife for not only their ignorance of airguns as ideal small-game hunting guns, but so much so as to effectively infer all airguns illegal for hunting. I probably criticized other individuals, businesses, manufacturers and agencies, but the aforementioned are the most pertinent to this thread.
In a phone conversation with a
Manic Compressive buyer a year or two after it came and went he said, "Congratulations on changing the Texas airgun hunting laws." Having not made the connection myself virtue of
my superhuman powers of humility 
, I asked, "Whad'ya mean?"
He explained that before
The Manic Compressive the only provision in the Texas game laws for hunting with airguns was
they were illegal for hunting game species. The year after
The Manic Compressive, airguns were recognized;
specifically as LEGAL for hunting NON-PROTECTED species.
It was over two decades after that small step for Mankind that Texas Parks & Wildlife legalized airguns for ALL game species. That's quite a story also. But not only am I too tuckered-out to tell it now,
but happy to have NOT BEEN INVOLVED IN THAT!
