Penguin, Good on your rifle. I'd recommend getting outside of Portland- out in the sticks- as far as places to shoot goes. Get some place where it's safe and nobody cares whether you shoot or not.
Now, I recommend taking up handloading for the .30-06 if you haven't already. If you check out the Hornady 5th Edition manual, they show 50grs IMR 4064 under a 150gr RN SP bullet running something like 2800fps. The times I've seen this load used in a Ruger M77 MkII, it performed quite well in the departments of accuracy and killing power.
As for other comments, everybody wants to get so caught up in "finger off the trigger" and all, they miss the point altogether.
