Good topic. The "law" varies from state to state and government to government. The feds for instance, as they have a remarkable tendancy to do, stretch the law as far as the imagination will allow based on "evidence" no more substantial than the lies of a paid (with money or a lesser sentence) informant. The rules of evidence established by the war on drugs apply; which means that no rules apply until the government establishes them in a given case, and then changes them on a whim.
Until quite recently in Texas, an ex-felon could own and possess a rifle or shotgun on his property provided that 15 years had elapsed since the completion of his sentence including any form of supervised release.
I found it, it did change from 15 to 5 years! I don't know what the current law is, but per my copy of the 1995-1996 Texas Concealed Handgun Laws 46.04(a)"A person who has been convicted of a felony commits an offense if he possesses a firearm: (1)after conviction and before the fifth anniversary of the person's release from confinement following conviction of the felony or the person's release from supervision under community supervision, parole, or mandatory supervision, whichever date is later; or (2) after the period described by Subdivision (1), at any location other than the premises at which the person lives. (b) An offense under this section is a felony of the third degree."
In Oklahoma, an ex-felon can possess firearms during the course of his employment as a gunsmith.
As easily as one may become a convicted felon in this day and age, it surprises me that some participants in THIS forum are so dogmatic as to buy into this prohibition nonsense. As with gun regulation in general, ex-felon prohibition punishes the innocent for the acts of the guilty. The ex-felon who will rob, rape, or murder you cares not that it is illegal for him to have the weapon that he is doing it with. The only ex-felon who will be deterred is the individual who truly is leading a productive life and who also can fall victim to a violent crime.
How easy is it to become a felon? Well, lets look at the Texas Statutes again. Committing the following horrible and evil act will cause me to be guilty of the same third degree felony as the ex-felon who is sitting on his sofa in his living room and has a shotgun under his bed 4 years and 11 months after his release; and the same felony as the ex-felon carrying a shotgun on his way to do a home invasion and murder at the home of the first felon.
What is that horrible act that places me, a CCL holder from Oklahoma (OK CHL honored in Texas) and the employee of a federal law enforcement agency in the same criminal class as the above ruffians? Well, according to 46.035 of the Texas Concealed Handgun Laws sec. (b) a (CHL) "holder commits an offense if the license holder intentionally, knowingly, or recklessly carries a handgun under the authority of Article 4413(29ee), Revised Statutes, regardless of whether the handgun is concealed, on or about the license holder's person: (1) on the premises of a business that has a permit or license issued under Chapter 25, 28, 32, or 69, Alcoholic Beverage Code, if the business derives 51% or more of its income from the sale of alcoholic beverages for on-premises consumption;"---an offense committed under this subsection is a "felony of the third degree."
So, if I take a trip to Dallas next weekend and eat in one of the many excellent franchise eateries that also serve alcohol for on premises consumtion, and during the course of my meal, the Wild Bunch from Arligton Stadium come in and start dropping $100 bills on booze at the bar, and the alcohol sales of the franchise eatery exceed 51% of the total sales, I then become a felon waiting for an arrest and conviction due to the fact that I 'recklessly' carried a handgun into the premises; reckless because any "reasonable" person knows that at any point in time the sale of alcohol could exceed 51% of sales.
