Can ex felon own and hunt with rifle or shot gun?
Pursuant to federal law, a felon cannot own a "firearm". But while felons cannot own guns, an "ex-felon" can. An individual can become an ex-felon in one of two ways: having the conviction vacated (overturned) by a court, or obtaining a pardon from either the governor (state offenses) or the president (federal offenses). In either of those circumstances, gun ownership rights can be restored.
In some states a felony conviction can be "expunged"; that is while the conviction is not overturned it is cleared from your record. However, state expungement or "restoration of rights", does not change federal law. Insofar as federal law is concerned, a state expungement or other restoration of rights, is insufficient for purposes of possessing a firearm.

Many states have rules and regulations stating that anyone that has been convicted of a felony in the state is not permitted to own a weapon, such as a gun/rifle. The reason for this statute is, among other things, that owning a gun is a privilege and people that commit felonies are considered often irresponsible and/or dangerous. Plus, there are studies done that most deaths that occur with firearms are committed by people who have felony records. I suggest that you meet with a lawyer to discuss whether your particular state has any regulations about who can own a gun for hunting. Most lawyers will meet with you the first time for free.
