Let me begin by saying thank you to everyone here on the forum! I am back in reloading and shooting sports after 15 years, and the forums have been a great help.
I am working up loads for 9mm to use in 3 Gun and other local matches. I am currently using a M&P Pro, bone stock.
The issue I am running into is that the loads are giving lots of stove pipes or FTE's, along with long soot trail down one side of the case. Here are a few of the loads:
Dardas 147gr, 3.2 TiteGroup, CCI SPP, various brass 1.112 OAL
Dardas 147gr, 4.0 WSF, CCI SPP, various brass, 1.112 OAL
Dardas 147gr, 3.7 HS-6, CCI SPP, various brass, 1.112 OAL
Dardas 125gr, 3.0 Clays, CCI SPP, various brass, 1.125 OAL
Dardas 125gr, 4.0 WSF, CCI SPP, various brass, 1.125 OAL
Now, let me put this out there as well..... (and probably answer my own question at the same time). I am using a Lee Autodisk, and need to verify powder drops. Is the soot from too little pressure to expand the case, and FTE/Stovepipes from inadequate pressure? Thanks for any help. (bad cell pic of cases attached)
