I just acquired a nice rifle with Sako L461 short action and barrel signed by "C.C. Seitz Pendelton, Oregon" . Caliber is 17-221 Remington which I understand would be the .221 Remington Fireball necked down to .17 caliber. Feels like a one ounce trigger. All in a beautiful custom stock. I know Seitz became pretty famous for his single shot trap shotguns and I learned that by web searches but could find no word about his rifle barrels. Can anyone shed some light?
