I have a number of friends who shoot driven birds, throughout the season, using only their Hollands, Grants or Beesleys. On some shoot days they may be putting up to 500 rounds through those guns. They were built to take it and still are, some 80 odd years after their guns were built.

I really don't think you need to worry about putting 2000 rounds through a Jefferey and I hope that you have a great deal of enjoyment doing so for many years yet.
