I know you mentioned you are doing it for fun, and that is just as good a reason as any to reload. You can buy flats of Federal and Remington target load in 12 and 20 gauge for much less then you can reload those gauges at retail prices. If you aren't buying supplies from Hummasons or Lawry's you will be paying retail prices which can be as much as 50-70% more. If you are serious about saving money in your sub-gauge guns then it's worth the drive to Hamilton to stock up.
