I have a 450 Marlin with a 15 inch barrel and a 308 with a 15 inch barrel for my T/C Encore. It's also a rifle cartridge. Seems like the WDFW should make it very clear in the regs. What is a " revolver type " of gun ? Since it's not a " rifle ", it's a handgun. These rules were probably written years ago and need to be addressed to avoid any confusion. I'd hunt with either as a handgun.
