I've used the GT .45, 225 gr. @ 830 fps in my 3" model 25 with the similar results as Andy52.
I've also used the 145 gr. .38 @ about 830 fps with good results.
If I remember right the .45 stopped in the 3rd gallon water jug and the .38 stopped in the 4th or 5th.
I didn't notice any leading. But the bullets are very soft and I don't think I would want to push the velocity much , if any higher.
