Sorry I have been away from this thread for awhile, I started a new job and got sick at the same time.
Took the 629 to the range with some 240 grain LSWC loads that I worked up for it and it loves 7.5 grains of 231.
I also shot the Speer 200 grain Gold Dot Short Barrel factory loads in .44 Special and Magnum as well as Factory Federal 240 grain JSP's. The revolver was a pleasure to fire with all of them and did not get really sporty until I fired the full power Federal JSP's.
Here are the results at 15 yards, some rapid double action. I used to test at 25 yards. But the older eyes are not up to that anymore. The revolver probably shots better than this, but its what I can do.
