I don't make a habit of carrying a rifle in my truck, but I was curious if i wanted to keep one behind the seat of my truck what the law has to say about this.  Is it a concealed weapon?  Is it OK?  Never been to sure about this.
Thanks

OK.  I sort of answered my own question but I am still a little confused about the wording of HB1028. It seems to say that no law may be passed preventing me from keeping a firearm locked in my car.  That seems to indicate that it is OK now.?  Additionally I amconfused by the wording saying something about in or on the owners property?  Does this law only apply to my property? Anybody out there understand this???      

Oops.  Forgot the wording.

Synopsis: Firearms and self-defense. Prohibits the adoption or enforcement of a policy or rule that prohibits or has the effect of prohibiting an individual from legally possessing a firearm that is locked in the individual's motor vehicle while the motor vehicle is in or on the person's property

From HB 1028

Should be just fine to keep it behind your seat, in a gun rack, in the trunk, or whatever.

It is illegal to have a round in the chamber, however.

As far as I know it's legal to carry a loaded rifle in your car.
I went here:
www.in.gov/legislative/ic/code/title35/ar47/
and checked a few places and I can't find anything prohibiting it or even talking about firearms in a car.
There are rules regarding spotlighting and weapons, check dnr regs for that.

JimTH is correct.  The law is silent on long guns, except for some hunting regulations.  That means there is no law prohibiting having a loaded long gun on your person or in your vehicle.  

As far as hunting regs go, the only prohibition with which I am familiar is that your long gun must be unloaded while you're operating an off road vehicle while engaged in hunting.  I don't know if that's merely administrative, or if it carries potential criminal liability.  In any case, it has no bearing on someone who is not hunting and also operating an off road vehicle.
