ODFW made a change to the muzzleloader regs for 2019. It removes the bullet length and jacketed bullet restrictions from the regs. Only thing prohibited now are sabots or any thing with plastic on it. Change is in bold/italics. If you have a fast twist rifle like a Gibbs the change makes it workable in Oregon now.
