I've checked online, people are specifically indicating "post recall" on used 700s, forgot to tell him that.If you want to really have a good look at the bore, spend a few bucks on a bore light. If not, open the bolt and hold a piece of white paper there while looking down the barrel.
The Remington 700 is a very good rifle. I hunted with one in 7mm Mag for years. Loved the rifle, but iffy on the caliber. But be aware there have been some issues with safety in the 700. Make sure you get it checked out and that it is in good shape.
The Ruger American is a very good rifle too. Don't dismiss it merely because you have one good experience with the Remington.
Personally, I think the Ruger #1 is the best hunting rifle. I have had one for several years and it is still a dream gun. It is 3 or 4 inches shorter than a bolt action would be with the same barrel length, so it is handier in tight spaces. It is as accurate as I need, and I think it is a beautiful gun to look at.
