Seriously looking at a Model 12 (308) as a starter precision shooter. Once or twice a year I may shoot out to 500 yards, but my local ranges max out at 100 and 200 yards. I can't hunt with this gun (in Indiana) so it will be a range & paper toy only. I am very interested in the Model 12 low profile/single shot. Any advice would be appreciated.

Also, how would the model 10 differ for these same desires? I'm not interested in getting a $1,000.00+ starter gun.
