While i won't tell you how many remingtons i own to avoid being called a remington extremist i will say they IMO are the best rifles made.
Now after saying that i will say i can't bring myself to buy a remington 700 at this time. i have a personal problem with the ISS ( integrated security system) . i can't spend the kind of money they want for them and get a peice of plastic sticking out of the bolt shroud. the floor plates are cheap pot metal wit a sprayed on finish that peels off.

Older remingtons i will buy all day long. but as far as particular years or sn# sequences no i can't say what is better.
