Not sure if you have enough points yet with 5, but for big muzzleloader bucks in OR you can't beat the Juniper hunt. The hunt is over thanksgiving so you got the rut working for you. I went with a friend a few years back and saw probably 40 different bucks in the area, many of them ranking as the largest deer I have seen in Oregon. The only problem is that they only give something like ten tags for it a year. Good if you draw, but makes the odds of doing it pretty low. Good luck!
