Titewad is an excellent propellant for 12 gauge target loads. I use it almost exclusively for 7/8 and 1 ounce loads. It has applicability for 1-1/8 once loads, but I consider it to be somewhat on the fast side for these. (It is a little faster burning than Clays or Red Dot.)
My standard skeet and non-handicap trap load is:
STS hulls
7/8 ounce #8-1/2 shot
16.5 grs. Titewad
Winchester WAA12L or CB0178-12 wad
Remington STS primer
This load is essentially a 20 gauge target load in a 12 gauge hull, but it patterns nicely in my shotguns and is very pleasant to shoot. Hodgdon's data (2004 Annual Manual, page 156) shows 16.9 grs. Titewad with this component selection as producing 1250 fps at 8,200 psi.
One could use the Remington TGT12 wad (green) or the Winchester WAA12SL wad (pink), but I do not like the crimp these two wads produce with 7/8 ounce payloads. On the other hand, either of these wads work very well with around 17.5 grs. of Titewad with a 1 ounce shot charge.
For me Titewad burns very cleanly, being about as clean as Clays itself. It meters very well through MEC and Hornady bushings, and I've had no problems with it migrating around the charge bar of Grabbers, the RCBS Grand, or the Sizemaster.
