I used to live in Tsawwassen.
Try visiting Brian at Stillwater Sports in Ladner if he is still in business. I always enjoyed his shop, and he is a wealth of local info.
Don't know if they still do Brant on Boundary bay, but that was always a hoot.
Richmond gun club was always a nice place to visit, and the folks were quite friendly.
There used to be a private hunting lease club around Boundary Bay where we used to hunt pheasant in the berry fields. If you are interested I can get in touch with some of my old Buds and see if they are still members... maybe they will cough up contact info.
Good luck
