IMO Pyrodex is more stable and consistent than T-7. And it is also a lot cheaper. So I am not surprised that it keeps on selling. Actually what amazes me is how willing shooters are to pay the outrageous prices of some of the new MZ powders. I have went back to straight black powder only. And with a little load development I personally do not believe any other powder is any more accurate. Including the ridiculously priced BH-209. Tom.
