I love my 60's...
All of which are extremely accurate (sub 3/4" at 50yds with off the shelf ammo) with scopes... I have a hard time with their iron sights.
That being said, my newest 60 (new? haha, 1993) in black synthetic has been cleaned ONCE since it's purchase... I've put 500+ rounds per sitting through it, with a maximum of 3-4 jams or misfires...
They all seem to love Federal Champion Bulk Packs (HP's, High Velocity) But do very well with just about anything (except remington golden bullets, and winchester X-perts).
I went shooting with an old high school buddy about a month ago, and together we put 525 rounds through my marlin (federal bulk pack) with ZERO jams or misfires (remember, this thing hasn't been cleaned in years). We spent the remainder of the day finding the best price locally, and he went home with a new model 60.
