Just bought a rifle from a friend, who lately, I come to find out has been over exaggerating prices to make one feel as of they got a good deal. Anyway, I bought a Remington 700 300 ultra mag from him. It's the Rocky Mountain elk foundation edition, with camo stock and stainless barrel. It's in good shape, a small scratch on barrel, but functions well. It was also professionally ported. I paid 600 but lately I'm really second guessing him and really not sure about pricing. New to this and would just like to know, one way or the other. Also are there any good sites for firearm values, one could reference in a pinch?
