As already stated, taking guns named in OIC's and changing them to restricted (or in SOME cases maybe even non restricted) and getting AR15's with N-R length barrels un-restricted, would be a great start.
I would also really like to see some cases where normal capacity magazines would be allowed, and maybe use that as a stepping stone to get rid of mag-cap limits. Say for 3-gun and IPSC/IDPA type stuff, if you are a member of a league you can use normal capacity magazines... Again, when the sky doesn't fall it would be a start at getting rid of the limits altogether.
The mag limits have practically killed most of the competitive shooting in Canada, and it would also stimulate the economy (more shooting leagues and people buying semi-auto rifles).
But the key here is baby steps, all our rights didn't get stomped on in the span of a year, it was slow and steady, and that's how we need to undo it. I doubt we'll see all our rights restored in most of our lifetimes if things keep going out way, BUT its a start and its for the shooting community in its entirety, and our future shooting generations!
