If you're in the Vancouver area, you should get out to see the Mission Rod & Gun Club. A great 300M range, lots of good freindly shooting fellas that shoot F-class - which would be a great class for you to try with your rifle- and the range host several great shoots throughout the year. PoCo is a busy place with a 200 yd range, TMSA.org in Pitt Meadows is small but expensive (50 + 100 yd rifle but good pistol facilities)
If you'd like to jump in with both feet, come up to Kamloops in September and try the Frosty Farky 300M match. There is a post with some details on the sight plus you can check out ktsa.ca
