Haven't fully wrung out my 541S yet, but it is holding it's own against almost all my target rimfires except maybe my 40X and 52C and is giving them a run for their money. From what I've read, the 541S has a "semi-match" chamber (whatever that means) and a hand lapped barrel. So, even if the outside is a little rough, that an be fixed as long as the chamber and bore are in good condition. I've seen several that the outside showed signs of hunting wear, but the internals were pristine and still shot like a target rifle. Like most accurate rimfires, they are ammo specific. Once you find what they like, they are your best friend.
Looking now for a 541T to go with the 541S because they handle and shoot so well. May have to take a chance on a Rem 504 also if I can find a decent one for a reasonable price...
