The Marlin is a fine rifle but for an Appleseed you really want a 10/22 and at least 3 spare magazines. That's because the second day is almost entirely shooting 40rds for time and accuracy and mag changes are a part of the activity. But yes you could get by with a Model 60 if you had to.
Do plan on adding a sling.
