EDITOR'S NOTE: This is an update of a post I did about four years ago.
About this time of year many Iowans get the urge to head out to the field and do a little hunting and one of the things that happens is that there's a fresh crop of felon in possession charges that come across the county attorney's desk. Often the offenders are people who may have had a third operating while intoxicated conviction a few years ago, and memory has faded. I had more than a few at the county attorney's office myself. There are also a number of people who have had convictions for domestic violence or who are subject to protective orders who ask the same things.
One question that always gets asked is "Well, can I hunt with an antique weapon like a muzzle loading rifle or shotgun?" The answer is decidedly "no", even though some folks may argue that federal law doesn't forbid it.
Our state has not specifically defined a "firearm" in the code-such things are subsumed in the definition of a dangerous weapon found in Iowa Code Chapter 702, which specifically exempts a bow and arrow possessed for hunting and other lawful purposes. In State v. Lawr, 263 N.W.2d 747 (Iowa 1978) the Court did say that a firearm is a small arms weapon from which a projectile is fired by gunpowder. It must be able to propel a projectile and it must do so by explosive force.
The last time I did this piece a fellow took issue with me, saying that black powder and pyrodex are not gunpowder and therefore a muzzle loader is not a dangerous weapon subject to regulation. I would like to see that fellow try to sell that to the veterans of the Civil War, but nevermind.
There's a recent case from Nevada that applies. In State v. Pohlabel, a defendant argued that the state's statute prohibiting felons from possessing firearms violated his second amendment right to keep and bear arms. Pohlabel's argument was that 18 U.S.C 921(a)(3) does not forbid felons from possessing antique or black powder firearms:
