mach1soldier Posted September 9, 2019 Share Posted September 9, 2019 8.0 at 1.165 for hs6. You will need closer to 8.3 to 8.6 depending on your gun / Popple holes. Link to comment Share on other sites More sharing options...
zzt Posted September 9, 2019 Share Posted September 9, 2019 Do yourself a favor and start with the AA7. Load to at least 1.160" as long as it passes the plunk test. This article should help you out. https://www.ssusa.org/articles/2018/1/9/how-to-use-9-major-in-a-short-barrel/ Link to comment Share on other sites More sharing options...

Full Size, 5.4 barrel, full length slide, short dust cover, 4 holes in the barrel. 2 Vees at a 45 and 2 popples. I believe all are 3/16 but I don’t have it to measure. I would need to load at a 1.165 Edited September 11, 2019 by jbultman Link to comment Share on other sites More sharing options...

I don't know how compressible AA7 is. If it isn't, I'm not sure you will get enough powder in the case under a 124 @ 1.165" to work all those holes and the comp. You may have to go to 115s and use the 124s for minor steel loads. BTW, Major Pistol powder is the same speed as AA7, and it is very compressible. You can try some of that.

My full size CK guns have 3 x 3/16" popples in the barrel. 170PF loads for it are: 9.9 grains AA7 for MG124JHP @ 1.185 OAL with CCI-500 10.7 grains AA7 for MG115JHP @ 1.165 OAL with CCI-500 I've loaded up to 11 grains AA7 and its no problem. 9MM case holds 13.8 grains of AA7 to the top.

YellowShooter Posted October 1, 2019 Share Posted October 1, 2019 Glad to have found this thread! When you guys measure the bullet with a JHP, do you guys measure from the flat. of the rim to the flat of the JHP? Or do I need to use something like the Hornady Comparator that measure from the ogive. I need to develop a load that would work for both these guns using: HS-6 and DP 124 JHP. - Open 2011 middy, with 3 port comp and two 3/16 poppel holes - CZ CM Factory Thanks!

If you are 'plunking' to determine go/no go, it doesn't matter where you measure from, as long as it is consistent. Link to comment Share on other sites More sharing options...

That's actually not much for holes being they're all the way out at the end of the barrel of a full size gun. It'll be plenty good with about 9.X gr of No.7 and a 124 jhp.

Nonsense. Only use 3N38 for 9 major if you enjoy cleaning up spilled powder on the shell plate, struggling with compressing the powder and watching your rounds grow in OAL after a bit.

I had none of those issues as long as I went slow and placed bullets by hand. That is slow, and I don't like slow, so I sold all of my 3n38 and switched to Silhouette so I could use my bulletfeeder again. Link to comment Share on other sites More sharing options...
