Thanks for all of the replies. I rarely get away from published load data and I appreciate you all sharing knowledge with me. Here is an update from this weekends range test. I loaded up some test rounds 2.9 grains of 231 with a oal of 1.097, 3.0, 3.1, and 3.2. working with a Chrono and paper I discovered I needed to drop this entirely. Poor accuracy and more than comfortable variations in velocity. 2.9 grains were ok 30fps deviation. when I got to the 3 gr I found a problem. 85 fps deviation and notable difference in recoil. I stopped there. I did not even try to shoot the rest. I was getting uncomfortable with how it was going. the purpose was to find better accuracy and things were definitely headed in the wrong direction. I normally load 3.1 to 3.3 grains under 147 grain xtreme loaded to 1.16. runs about 3.5 inches at 25 yds. I was hoping to find a combo that did better. Thanks again all.

I got in 2 sample packs of Eggleston 9mm 147 and am looking for a place to start. I wanted to use either TG or 231. I am not finding much data on lead with these 2 powders. The biggest problem seems to be a really short throat on my M&P. I have loaded some dummy rounds to find the max length I can use and here are the results. .357 dia. 1.100 oal w/.381 crimp size will plunk and spin. .358 dia. 1.098 oal w/.380 crimp size will plunk and spin. (barely) If I back off .005 will this be too short to load safely ? 1.095 and 1.093 respectively. How would I figure out a good starting load?

Hi all. Been shooting 3-gun for about a year now and found this forum while looking for practice techniques and reloading info. Great info from a lotta good people here. I have gotten a lot out of it already. I look forward to learning more and gaining enough knowledge to be more of a contributor!
