From The Truth About Guns:

The beginning of fall signals not only the return of the school year but also the beginning of hunting season. To prepare for many hours to be spent hunting with a gun in a duck blind or a deer stand, hunters need to equip themselves with ammunition, various outdoor gear, and maybe even a new firearm.
That is why some states have tried, are currently trying, or now have a Second Amendment tax holiday where people can purchase hunting supplies, ammunition, and firearms without the burden of sales tax. It’s reasonable to assume many hunters may spend somewhere around $500-$1,000 on supplies to start a hunting season so the opportunity to save $50-$70 (depending on the state) on those purchases translates to significant savings for many individuals and families.
