TimWarner Posted March 8, 2008 Share Posted March 8, 2008 http://home.comcast.net/~twarner21609/photo/major9.xls I compiled a lot of the data from the major 9 threads into that there spreadsheet. You can SORT by powder, bullet weight, etc. Link to comment Share on other sites More sharing options...
fastshooter03 Posted March 10, 2008 Share Posted March 10, 2008 Turned a regular length 9x23 into a 9major last year and was using a N330 load which was working great with little muzzle blast. The only problem was with mags and ejection but we never really had time to fool with it. We're making a 9 shorty this year just for the heck of it. I plan to use Hs-6 and Silhouette for practice matches and Vhit for bigger stuff. We stopped using 3n37 a few years ago due to the DEBRIS it left behind. N330 and N350 with WSRs is what we currently like. Nick Link to comment Share on other sites More sharing options...

mpolans Posted March 10, 2008 Share Posted March 10, 2008 Shouldn't this have been moved to the reloading area a while back? Link to comment Share on other sites More sharing options...
BOGA Posted March 13, 2008 Share Posted March 13, 2008 The powders I am using for major 9 were already mentioned and almost same load as them My powder of choice is 3n38 and when its hard to find it, I use 7625 which is readily available from my shotgunning friends. My 38 super powder is 7625 and for my semi-retired 9x23 is also 7625 Link to comment Share on other sites More sharing options...

JThompson Posted March 24, 2008 Share Posted March 24, 2008 (edited) what debris? Grains of unburned powder most likely... I had the same thing with mine... it looked like sand in there. silhouette is good stuff, meters well, fairly clean and is cheap.didnt see anything as far as pressures go that alarms me. Harmon I agree with you. Edited March 24, 2008 by JThompson Link to comment Share on other sites More sharing options...

RiggerJJ Posted August 3, 2008 Share Posted August 3, 2008 Just completed a 38sup to 9mm conversion of an open 5in sti, crono'd ammo, got GREAT tuned (svi) mags from Mileninum Custom, and shot my 1st match. Thought I would share load data; 7.4 gns HS6 w/ montana gold 124 CMJs = 150ish PF. (for "outlaw" 3gun matches, its primary use) 8.3 gns HS6 w/ montana gold 124 CMFs = 170ish PF. (for uspsa matches, major PF) both are loaded to 1.165 the major loads are not compressed, and show just a small amount of primer flattening, no primer flow or firing pin damage. The gun runs like a top, which I attribute to both Steve Moore (Denver) for fitting a great gun, and the great job Millennium Custom did on tuning the mags. Dot travel in the c-more is in a tall skinny oval shape, stays in the window during the shot and recovery, and is very predictible. Looking forward to shooting more with this gun! disclaimer; YMMV! jj Link to comment Share on other sites More sharing options...
PJONES5 Posted August 4, 2008 Share Posted August 4, 2008 I'm looking for some starter points for my 9mm sti to shoot major with.

Txkid Posted August 4, 2008 Share Posted August 4, 2008 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? Link to comment Share on other sites More sharing options...

I haven’t made any changes to the STI any suggestions? And also what does “SD” and “ES” stand for? Guess it's just the differences in guns. I too use Longshot and HS6 with 124 Precision Delta fmj. 7.4 Longshot loaded to 1.170 gets 170 PF 7.8 HS6 loaded to 1.170 gets 170 PF Longshot is a tad cleaner. HS6 more consistant. No flat primers with either. I use mixed brass and WSP. This is out of my Para Open gun with a STI TruBore S2. Craig Link to comment Share on other sites More sharing options...
Txkid Posted August 4, 2008 Share Posted August 4, 2008 (edited) 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.

Txkid Posted August 10, 2008 Share Posted August 10, 2008 TxTry using Winchester Small Rifle primers... A-G All-Gator, Today I did some testing with WSR Primers and the Primer Pressure Sign has diapered. But I have notice the FPS dropped 10~30 with the same powder load. Anyway I was able to get 170PF , 124gr 1.180 OAL with 8.0gr Longshot 8.4gn HS-6 Thanks for the advice Thomas Link to comment Share on other sites More sharing options...
