That sounds like a nice shooting load. 3.5gr of titegroup with 130gr.
I use 3.7gr with 124 plated, and 3.3gr with 147 plated.

Almost exactly what I do with these weights. Although with the 124's I have found that Win 231 is more accurate in most of my other handguns. Now that i am well stocked on TG, I may explore a little there again.
