Kevin,
Both the M-60 and the 10-22 are good rifles, you can spend a ton of money on the Ruger. After spending all that money there are a lot of guns which will cost less and shoot better. One of the M-60's in my gun safe shoots very well with ammo it likes, a little better than the 10-22 I had for years. I bought the 10-22 in 69 and finally replaced it in 2002, it was as good as when I bought it. The Bushnell 3x9 Airgun scope with the adjustable objective is a lot of scope for not much money, makes it easier to hit small targets at 9x vs. 4x.
