7828 powder question

[blacksmithden]

What's the difference between IMR-7828, 7828SC, and 7828SSC other than the actual length of the grains?? Does this change the characteristics of the powder?

According to Hodgon, no difference at all in the burning rates.

It doses make it easy to meter though.

That's kind of what I figured. Thanks for the input.

And once you've used a SC or SSC powder you'll never go back. They are the greatest development in gunpowder since smokeless powder came in!
