Thank you for the information. I just purchased a sidekick, great gun. First time out used 2 50 grain pellets with a Hornady saboted load. Great results at 100 yards for a muzzleloader. Averaging 11/2 to 2. Certainly deer accurate. I was just looking for an alternative powder. After reading the information in the link, it appears triple 7 and Blackhorn 209 preform very similar the difference appears to be in cleaning, residue after shots and non corrosive. Three big keys. Thanks again.
