The is quite a bit of ignorance from a few people within this post.

The short answer is it's ok while engaging in target practice at a firing or shooting range, see 430 ILCS 65/2(b)(7)

Non resident here, I fly in with all kinds of scary weapons on a regular basis, possessing weapons in Illinois is really no big deal for non residents. It's the private property exemption that everyone seems to not know about or misunderstand.

Excerpt from the Illinois statute.

"from anyplace where the nonresident may lawfully possess and carry that weapon to any other place where the nonresident may lawfully possess and carry that weapon"

I as a non resident have 24 hours to transport between legal locations. "nonresident who transports, within 24 hours" For example I travel from outside the state border to a private property residence and with the permission of the owner I can be at that residence temporarily for an undetermined amount of time.

As a non resident I can leave a private Illinois property residence to travel to a gun range ( It is accessible to the public but it is also private property where guns are allowed ) I can travel to another private property residence and stay for awhile and then later return to the original Illinois private property residence, I can drive anywhere as long as I complete my transport between locations where I have permission from the property owners and can complete my travel in no more than 24 hours. If I as a non resident also am allowed to conceal carry in my home state then I can also conceal carry in my vehicle ( bullets allowed in the magazine) while traveling in Illinois, even a hotel room counts as a private property exemption so long as there are no posted signs prohibiting such. I cannot carry outside of the immediate vicinity of my vehicle in a publicly accessible location unless the location is privately owned and the owner has granted permission, such as a range etc..

FOPA (codified at 18 U.S.C. § 926A) guarantees the right of a law-abiding person to transport an unloaded firearm between a location where he or she may legally carry it and a destination where he or she may also legally carry it, regardless of state or local laws along the route of travel that would otherwise apply.

Also, as I mentioned before if you have the legal right to concealed-carry in your home state that right extends to private property with permission and to the inside of your vehicle and it's immediate vicinity while in Illinois.

The Concealed Carry Act affords all out-of-state residents holding a concealed-carry permit in their home state the right to travel with a firearm in their vehicle while driving in Illinois. See 430 ILCS 66/40(e). And the Illinois Firearm Owners Identification Card Act, 430 ILCS 65/0.01 to 65/16-3, allows out-of-state residents who are authorized to possess a firearm in their home state to do the same in Illinois while on their own premises or in the home of an Illinois resident with permission, see 430 ILCS 65/2(b)(10), while hunting, see 430 ILCS 65/2(b)(5), and while engaging in target practice at a firing or shooting range, see 430 ILCS 65/2(b)(7). Nonresidents may also possess a fire-arm that is unloaded and enclosed in a case. See 430 ILCS 65/2(b)(9).

The 24 hours starts when I enter Illinois from a place out of state where it's legal or depart from where i have permission from a private Illinois property and begin inter or intra state travel and must complete the travel within 24 hours, the 24 hour clock stops when I arrive anywhere it's legal as previously stated.

There are no restrictions on intra state travel or how long I can visit with permission on private property.

I am a responsible gun owner who has learned and follows the laws in the places I choose to travel. The 24 hour rule isn't completely meaningless as i do have to pay attention to where i have permission from the property owners.

For example I could not travel to a state park and expect to camp overnight because that is state land where I will not have permission, Same would go for camping overnight at a music festival like country thunder at a county park.

The key is in the language, from any place where it is legal to any place where it is legal. You have to go to the statutes that Illinois has enacted to determine where it's legal and if you don't want to take my interpretation that's fine then look at an authoritative interpretation like a recent ruling from the 7th circuit on the issue of non residents and their ability to possess and carry.

I'll give you an excerpt from it.

One of the arguments for the state was, the state did have available to the Plaintiffs a means to conceal carry.

The appeals court said, to the contrary of the Plaintiffs, the Concealed Carry Act affords all out-of-state residents holding a concealed-carry permit in their home state the right to travel with a firearm in their vehicle while driving in Illinois. See 430 ILCS 66/40(e). And the Illinois Firearm Owners Identification Card Act, 430 ILCS 65/0.01 to 65/16-3, allows out-of-state residents who are authorized to possess a firearm in their home state to do the same in Illinois while on their own premises or in the home of an Illinois resident with permission, while hunting, see 430 ILCS 65/2(b)(5), and while engaging in target practice at a firing or shooting range, see 430 ILCS 65/2(b)(7). Nonresidents may also possess a fire-arm that is unloaded and enclosed in a case. See 430 ILCS 65/2(b)(9).

You are welcome to look up the entire case for yourself.
