As TimS says, circa. £1000. A little tricky as it is a bit expensive for a first time buy and those trading up may want to go for one of the newer stocks. Some 50m test groups will help a lot as will indications that tend to show the amount of use the rifle might have had.

PM me with an email address and I shall send you an article about buying second hand target rifles. That will help you judge how it might be assessed.
