NSRA has a target rifle program which includes F class and also a small group of precision rifle shooters, which is essentially military sniper matches.

Pretty much everything you need is here.
Pretty active in the summer, not so much in the winter. I'm trying to get someone to go out over the next few days for some long-range stonking but there is snow in the forecast.
I'm getting into F class this year, will see you on the range no doubt.

edit: Hey just noticed you're move is done! Awesome, welcome back to the right coast! Yarmouth has a beautiful indoor range, as I'm sure you'vbe already found.
I'm working with another CGN here in NS to put together an unknown-range practical rifle match. Basically a 100 acre ranch with 10-12 stages of rifle fire 4-6 rounds per stage at unknown distances from 100 to 1000 yards in field conditions. Shooters will be given a shooting position and told there are x number of targets between two geographical features and given a start signal. Points divided by time gives hit factor. Targets will be IPSC targets at 90 degrees. LRF or milling permitted, you must hike with all you gear from range to range.
