upreme Court Says Muzzleloaders are Legally Firearms
Cheyenne- Posted 6/28/06
The ruling comes in an appeal by a convicted felon who says he thought he was allowed to own a black powder rifle. Such rifles are excluded from the federal definition of firearms.
A spokesman for the Wyoming Game and Fish Department says the ruling will come as a blow to some Wyoming residents who have felony convictions in the past but who are now dedicated black powder hunters.
Governor Freudenthal says he would favor changing the state law to allow convicted felons to continue to hunt with black powder guns.
The court ruling released Wednesday upholds the conviction of Frank Alan Harris in a Casper court on a charge of being a felon in possession of a firearm.
According to the court ruling, Harris was previously convicted of aggravated robbery and robbery.
