Here we shoot 300M, 500M, 600M and 800M in a varying mix.
Some places do just 3-5-600yard, I hear some just do 800-900-1000yard.
Quite a few ranges now use electronic targets, some are in NB, PEI. There's no up and down at the other end anymore with those and saves a lot of $ by not having to build butts on new ranges, just a backstop and target frames.
Speeds things up a lot too. I hope we'll have that in NS next year.
I don't know if there's a minimum distance for Fullbore F-class, I don't see why there would be although at 100m it wouldn't be much of a match for wind reading and such.
You can do .22lr smallbore indoor F-class at 20yard/meters. .22lr would be real fun for 100M and 200M, maybe even 300M.
