with the price increase of lead shot, and the fact you can get the valuebox at walmart/canadian tire for 20 cents a round, it just isnt worth it. (in my opinion) ((unless you are shooting rare size shotshells such as 10 guage,16 guage, 28 guage which are hard to find, or competing in competition clays then maybe to control the quality etc))
I reload rifle rounds, and thats getting expensive too, but you get a better round tailor-made for your individual rifle at somewhat less money. If you want to use cheap bullets it can be alot less expensive.
