I've been reloading .45 acp with Hodgdon Titegroup powder, 4.3 - 4.4 grains, and I've noticed that it's very smokey... like almost black powder smokey. Is that normal for Titegroup? I'm using Sellier & Beloit primers. I don't get a big fireball like I would expect if all the powder wasn't burned by the time it got to the end of the barrel. Anyone have any ideas? I don't see a lot of soot on the gun when I'm done, like I've seen before with the Federal bulk ammo.
