I've had my second one for over forty years, and still regret trading off my first one. The older ones are superb rifles. Unfortunately they are expensive, but your granchildren will probably enjoy it with their kids.
Mine will be going to my son and his boys soon. I can't hunt anymore due to age and health problems, so I can't see making them wait for it till I croak.
