I shot ORA/DCRA Precision Rifle for a few seasons, with the occasional F-Class practice thrown in. It let me figure out my loads and shooting out to 1000 yards. PR is good because it has snaps and movers, depending on the range.
Not sure if anyone is shooting this in QC but you can shoot it at Connaught in Ottawa or if Tactical Teacher is running his excellent 2-day miniclinic and match in Petawawa. I highly recommend these as the kit you will need is similar to PRS. Also, the instructor is a whole lot of fun and they are good guys out in Pet.
The first PRS style match I shot was actually at Valcartier. Great crew out there as well, although my French wasn't good enough to understand all the jokes!

Even if the match is sold out, ask the Match Director if you can attend as a spectator. You will find the guys friendly and willing to help a newbie.
You can also sign up for clinics like the one at Meaford this spring. Even if the clinic is sold out, let the organiser know you would be interested in attending in the future.
There also tons of stuff on YouTube and Snipershide.com has a lot of info. Last but not least, look up the posts of our very own Kombayotch on this forum.
