I heard the Tripple 7 burns hotter than Pyrodex, therefore you have to use something like 5% less when shooting loose powder. Is this true, because I asked a salesman at my local gun shop, and he hadn't heard this. I am currently shooting Pyrodex RS, and I am thinking of trying 777, or Pyrodex RS select. I am not sure which I want to try. Any suggestions? I shoot a Knight wolverine 50 cal. inline. Thanks
