Best current powder for 6.5G?

[Harpoon1]

Isn't that what Federal uses with their TNT 90 Preditor load, which gives pretty great velocity? It's an older and not sexy powder, but really, not a bad choice at all.

I pulled some Federal 90 TNT rounds apart 6-9 months ago and I couldn’t match the powders up! And I think I have like 90% the Grendel powders. Under a jewelers loupe it was close but, when I looked at it under a “hobby” microscope, I didn’t think it was a match. Too be fair, I’m no expert and it could have been just lot to lot variability though.

Having said that, you could do a lot worse than using H335 with the 90 grn TNT’s!
