Effective chlorine (measured as chlorine gas), also known as % available chlorine) will always be lower than % hypochlorite. Effective chlorine let's you compare different forms of chlorinating compounds (liquid and powder) by standardizing to % available chlorine.

I go to an independent pool store that sells reusable cases of Hasa Chlorine (min 12%).
If you are interested in trying the Hasa stuff, just go to their website to see what pool shops carry their cases.
Happy sanitizing.
Thanks for this information. I went to the site and found a dealer a few miles away from me.
I called them and they sell 4 gallons of 17% for $16.99 and they are returnable jugs. If my calculations are correct that is a savings of 2 cents per 1ppm FC for my pool and no more stuffing plastic jugs into my recycle bin.
