New to predator hunting in Oregon

[doranSpenst]

I live in western Oregon. I have always hunted elk, deer, blackbear, and love to fish. I have been noticing over the last couple of years the declining deer populations and have become increasingly aware of the neccesity for predator management by hunters. Not only will I be helping the deer and elk populations, but will really improve my overall hunting and shooting skills. I only have a 300 winchester mag, and 12 gauge for the moment. I would really like to get a 22-250 or 204 ruger but funds are tight right now. I am trying to decide if I should invest in a used single shot or wait and buy a bolt action.
