Wish i could use em here in Oregon, i looked at them today... we have an "All lead bullet" requirement, side locks and iron sights only. those powerbelts have that plastic nozzle at the base making them illeagal to hunt with..no inlineseither for the muzzle loader seasons here, but you can use them in general season centerfire rifle season if you have balls enough to go out there and brave the crazy drunk road hunters....i quit high powered rifle hunting 20 years ago...too dangerous and too manyhunters out there in the woods...
