BTW, Has anyone tried Hodgdon H110 for 9mm major or is it too slow of a powder? Thomas

HoMiE Thank you very much for your information. I feel better knowing I am not the only one getting flatten primers with 9mm major.

I am having presser problems “Flat primer with normal strike” according from the following web page superdude pointed. (Great info!!!) http://www.38super.net/Pages/Factory2.html I am just making 9mm with 124gn, Longshot 7.8gn and HS-6 8.0gn mix brass, CCI primer. Gun STI Trubor GM The other day I called STI and was told to switch out the firing pin to an extended one and hammer spring to a softer one, I really didn’t know why but I guess this is to suppress the primers ignition to slowdown the burn rate of the powder. Also I was told for 9mm major the slower the powder the easier to make major? I have been reading information that points to a different opinion and confused. Any opinions to lower the presser and still make major?

Thank you All-Gator i will give it a try Thomas

Thank you HoMiE, so SD and ES is a Accuracy thing I get it now. I was wondering if by changing to a extended firing pin and the softer hammer spring thing might improve?? BTW, I have to add I am using mix brass and CCI small pistol primers. Thomas

I am new to reloading and just got a STI Grandmaster and am working on finding a major load. With Longshot 7.8gn, 124gn 1.180 OAL I was able to 167 PF And with HS-6 8.0 gn, 124gn 1.180 OAL 165 PF But whatever I do, I can’t get away from getting flatten Primers and was thinking if there is a way to lower the pressure? I haven’t made any changes to the STI any suggestions? And also what does “SD” and “ES” stand for?
