As far as I am concerned, T-7 is Part Smokeless, and I inherently distrust such in Black Powder Firearms! If YOU like it,WONDERFUL! I am Ecstatic for you! Just don't waste your time trying to make ME like it! I am REALLY HAPPY WITH my current way of loading, and I have been doing it for enough years to KNOW WHAT I LIKE! In fact I LOVE my semi-Duplex Load of a Goex Primer, and Pyrodex Main Charge! I simply ADORE the PYRODEX PELLETS! Until something new comes up, that satisfies the rather peculiar desires of my heart, I"M gonna continue to do things MY WAY! I may advise others to TRY my way, But if no-one wants to, That's fine by me! There are people you couldn't drag into Heaven, with a three-quarter inch lariat, and a 1,300 lb. Quarterhorse! That's Life!
