I second the Snappiness of TG.
I have tried TG with both lead and jacketed 147's and I settled on VV N-340. Slower, more even recoil impulse.

TG Load tried was also 3.3gr, mixed brass, Rem 1-1/2 SPP, 147gr LRNFP. My notes state Very Snappy, Accurate in both G-17 and BHP. Lots of Muzzle flip.

Good luck & be safe,
Bert


PS. You might want to look into VV Powders or (I'm trying this next) Clays (straight not univ.).

One of the things that I have found with lead rounds is that they take a slightly slower powder. This is because of the ignition impulse seems to be too fast to obturate the bullet in the barrel. Going with a slower powder adds duration to the ignition impulse and the presure spike is still building as the bullet enters the bore. This causes a more complete seal in the bore and as such causes less erosion leading and increases velocity and accuracy (for a given round).

The best 9mm lead load that I have is with VV N-340 and a TNT?Star 147 LRNFP (Sorry, but I don't have my loads notes handy). VV Powders are hard to find, so the next time I buy powder, it'll be "CLAYS". I hear very good things from everyone that shoots it (Many Calibers).

Also, any idea on how to cure the <black powder> effect? If my loads creats lots of smoke, would decreasing it change anything...
Mike, With TG, cutting back will increase the problem. TightGroup loves presure...
At lower levels, your load will get flakey and groups will fall apart. At higher presure (upper end near max) TG cleans up very nicely, the smoke goes away, and the group size gets nice and small.

"What slower-than-TG powder should I be testing under my 147's?"
Weshoot, I have had great luck with 147's and VV N-340. I have tried 231, WST, WSF, N-320, TG, Bulls Eye, Unique....
TG is nice for a fast impulse with jacketed rounds, but when it comes to LEAD, slower powders are the clear winner. Any of the aforementioned powders will work, but My favorite so far is the N-340.

It really boils down to what you are looking for in accuracy and recoil impulse.
I like heavy lead loads with Slow/Med speed powder for a moderate/slow recoil impulse. (The eyes are not as fast as they used to be).
