doug, for what its worth, i started my 11 year old son ryan out with a crosman raven. 550-575fps, and would easily group under a dime at 10m. it was plenty capable of squirrel size game at 25 yards or less if the shot placement was watched.
theyre fairly inexpensive, definitely kid friendly and has just enough heft to it for an adult.
ryan picked it over the gamo delta as it just "fit" hime better. ryan has since moved on to a winchester 800x and a gamo big cat.
another thought would be one of mike melicks tuned b16s with the synthetic stock....................
