Finally got out to the range to run some loads through the chrono. I've been trying to find a bullet/powder combo that I can settle on.

I had originally worked up a load of 5.1 gr of WST ( max load according to Hornady) that shot very well with NO signs of overpressure when pushing a 200gr HP/XTP bullet. I'm doing all this in a G30. After reading this site for awhile, I came to understand that I could go no higher with the WST powder, so I decided to try some other powders ro see if I could up the velocity a bit ( I'm thinking Corbon speed).

I'll just mention the higher charges I tried for the different powders ( these averages were all based on five rounds each, using Federal brass, Win. primers, and Hornady 200gr HP/XTP heads ).....

WSF= 6.3 gr, avg. vel. 773.14fps with an ES of 28.8fps.

WSF= 6.5gr, avg. vel. 783.3fps with an ES of 46fps.

Universal= 5.8gr., avg. vel. 744.5fps with an ES of 40.4fps.

Win. 231= 5.3gr., avg. vel. 727.9fps with an ES of 89.7fps ( YOW!).

Win. 231= 5.6gr., avg. vel. 787.8fps with an ES of 56.5fps.

Finally, the load I began with...WST=5.1gr., avg. vel. 824.2fps with an ES of 26fps. So for what it's worth as far as I'm concerned, the WST seems to be the most consistant of the group, and had the higher velocity I was looking for. An interesting side note is that I tried to chrono both Corbon and Hornady Critical Defense loads and couldn't get a reading on the chrono. From the recoil and noise level, they are definitely more powerful than my reloads, but alas, due to their cost, I wasn't willing to try more than two each. I did try some 9mm later that was in the 1170fps range, so the chrono was still working. I have no idea what the problem was. Now I just got to buy more WST.
