tyman1876 Posted January 1, 2019 Share Posted January 1, 2019 Out of my Chaos (3 holes) 9.6gr was a 172PF w/ a 124gr JHP. Link to comment Share on other sites More sharing options...
chevrofreak Posted January 1, 2019 Share Posted January 1, 2019 Try the Silhouette around 7.6gr for a 124. I run 8.3 with a 115 personally, and also liked 10.5 of AA7 with a 115. Link to comment Share on other sites More sharing options...

tyman1876 Posted January 1, 2019 Share Posted January 1, 2019 How is working for you.. I have a chaos in the making.. AA 7 is going to be one of my powders I just got finished testing 5 different powders. Hs6, WAC, Silo, AA7 and Shooters World Major pistol (Lovex). In the end, Lovex came out on time with AA7 a pretty close second. If you’re interested I have my data on all 5. Send me a PM if you want and I can send it to you.

22 shooter Posted January 7, 2019 Share Posted January 7, 2019 Guys, not sure if it's changed or not, but in years past AA#7 was terrible to erode barrels and comps Link to comment Share on other sites More sharing options...

BallisticianX Posted January 7, 2019 Share Posted January 7, 2019 1 hour ago, Shmella said: Im pretty sure that has been disproved as a real thing in recent years. That was an urban legend. Im not mentioning the names but the rumor was started by a gun builder years ago that had customer complaints of barrel erosion. The most popular powder at the time happened to be A#7 and happened to be used in the compliant guns. So it was used as an easy out excuse to divert the blame away from a bad batch of barrels. It was shortly after this rumor flew around the shooting sports someone did some high round count testing with A#7 and a few other powders and found no elevated levels of erosion from A#7 vs anything else tested. I cant remember whom did it but you can find it on the web. A few years ago the same scenario played out on Lil-Gun powder. A high end big bore revolver builder blamed premature throat erosion on his guns on the powder to divert blame and blemish of reputation. Again someone did some testing and found it was not the case but instead the barrel stock was a "softer than usual grade" That article is also searchable. I run A#7 in my 38 Super with awesome results and my barrels are just fine and as accurate as they were 8000, or 12000 rounds ago depending on the gun. Now to the point of the post, Ive never loaded A#7 in 9mm. Im intrigued now...The volume my 10.5 gr load takes up in a Super case looks like a possible overflow (or close to) in a 9mm case. Well if it feels and shoots like it does in my supers you wont be unhappy! Link to comment Share on other sites More sharing options...
Shmella Posted January 7, 2019 Share Posted January 7, 2019 I used to load 10.5 in 9mm with a 115. Wasn't even a compressed load. Was my favorite load. Im using 124 now only because my barrel is slower in my new gun than my last gun when i ran 115s Link to comment Share on other sites More sharing options...
22 shooter Posted January 8, 2019 Share Posted January 8, 2019 You could physically see the erosion of my comp. I'm just putting it out for info. Link to comment Share on other sites More sharing options...
