Hot rodding is exactly what I don't want. I have Ruger's and H110 for that.

I'm after what I thought TB is intended for. Ruger revolvers I've went way beyond anything published. I also had much younger hands to hold on to them with whe I was doing such. I have no desire to experiment with non published data using a Colt S/A.

If the 5.5 grain load doesn't seal up and clean up, I'll likely set it back in its place back of the shelf or use it for fertilizer.

I know I can bump up the Universal just a bit and it will clean up. Still a low density load in the big case and higher than desired velocity. I have and can continue to live with the Universal powered loads

The TB has the right density, meters fines, good accuracy for the few I've fired, and is in the velocity range I want.

If it were any dirtier, I'd be as be well to fire black powder, Pyrodex or Triple Seven.

Thanks for all the information, encouragement, and advice!
