Gun hunters are transitioning away to crossguns anyway, for more of the rut and much longer season. It went on for 10 years + here in Indiana. I have 5 guns, but am not a gun guy. I rarely touch them. 98% archery. I drew Illinois full firearm season public tags the last 5 years, and never used any of them. I'm too tired after 8 weeks of hardcore archery hunting. And last year I had already filled both my archery tags. There are so many xgunners on public these days I had to quit hunting from walk in areas and go strictly with boat access spots only.
I actually bought a new Savage 20 guage bolt action slug gun 6 years ago, which I still have never hunted with! Top notch scope too! I don't know how much the demand for that gun will be reduced by this legislation. I don't know how much benefit these rifle restricted calibers have over my quality slugger. Something to study. But my only rifle is a Remington .300 Win Mag for elk and stuff, which I rarely use, and which I doubt will ever be legal in Illinois. So I expect I'll keep my Savage.
