Thanks in advance, Andrew BTW I'm torn on what comp, either Carver Major or SJC Major. Link to comment Share on other sites More sharing options...
glocklover Posted February 7, 2012 Share Posted February 7, 2012 I'm new to open and I have not tried a lot of powders, but so far I really like 8grs HS-6 125gr bullet. Give it a try. Craig Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 7, 2012 Share Posted February 7, 2012 I really like 8grs HS-6 125gr bullet. Craig I used to use HS-6 - very nice in my STI TruBor. Just switched to WAC - like it better - 7.0 grains/124 MG JHP at 1.16". Jack Link to comment Share on other sites More sharing options...
Darrell Posted February 7, 2012 Share Posted February 7, 2012 Autocomp here, 6.8 gr @1.165 with MG 124 jhp in m&p open gun and STI competitor. Link to comment Share on other sites More sharing options...
9mmMike Posted February 7, 2012 Share Posted February 7, 2012 (edited) HS-6 has a progressive burn rate that is ideal for 9mm Major. I like it because of it's availability, recoil impulse, it's high consistency in pressures right at max, and it disposes bullets on target.

MoNsTeR Posted February 7, 2012 Share Posted February 7, 2012 HS-6, Autocomp, and Silhouette are your best options for loading short to fit Glock mags. I use 7625 currently but it will not compress to Glock-friendly OAL. Link to comment Share on other sites More sharing options...

buckaroo45 Posted February 11, 2012 Share Posted February 11, 2012 My G17 Open w/ SJC comp likes 6.8 Autocomp, 124 gr MG HP, Win SR primers @ 1.155 oal. Makes a comfortable 170 PF. Your results may vary. Link to comment Share on other sites More sharing options...
rupie Posted February 11, 2012 Share Posted February 11, 2012 I shot both hs6 and autocomp in my 9mm open glock I like autocomp better mostly because it is cleaner, I would clean it before the season starts and call it good! Link to comment Share on other sites More sharing options...
Steve RA Posted February 14, 2012 Share Posted February 14, 2012 Try 4756, it works well also. Link to comment Share on other sites More sharing options...
SLM Posted February 14, 2012 Share Posted February 14, 2012 Try 4756, it works well also. What's your load? Link to comment Share on other sites More sharing options...
lcs Posted February 14, 2012 Share Posted February 14, 2012 Try 4756, it works well also. In 9 Major ? Fills the case and I mean FULL. 4756 is a very fluffy powder and if I remember correctly--never would make major. (165PF) Link to comment Share on other sites More sharing options...
sweetback Posted February 15, 2012 Share Posted February 15, 2012 6.8-6.9 grns. AUTO COMP 1.145 O.A.L. 124 grn. MG/JHP FED. SRP REM/WW brass SJC 9 MAJOR 11 port comp 170 PF Link to comment Share on other sites More sharing options...
CocoBolo Posted February 16, 2012 Share Posted February 16, 2012 May favorites in 9 major in order of preference (2011 not tupperware). Silhouette, AUTOCom, HS6, AA#7. others that will get-er-done - 3N38, TrueBlue, WSF, N350, IMR7625, HS7, LongShot Link to comment Share on other sites More sharing options...
al503 Posted February 16, 2012 Share Posted February 16, 2012 You're loading short (compared to some other platforms.) I'd use the slowest powders (and the shortest bullets) available just to keep the pressure down as much as possible. I'd suggest N105 (yes you can make major with it in 9mm) 3n38, AA7.

surfmaster Posted February 16, 2012 Share Posted February 16, 2012 Could you share your Major 9mm recipe with N105? Thanks. You're loading short (compared to some other platforms.)

al503 Posted February 16, 2012 Share Posted February 16, 2012 Could you share your Major 9mm recipe with N105? Thanks. 9.6 grains, 1.19" OAL, Win SR primers, 125 grain Zero JHP out of a 4.5" shorty with 4 popple/bbl holes (Brazos ProSx) got me 168 pf. 9.8 grains got me 171. You can't get much more than 9.9-10 grains in the case. However, with a longer bbl and or no bbl holes, you could make major probably closer to the low 9's.

Steve RA Posted February 16, 2012 Share Posted February 16, 2012 I had one of the first 17L Glocks and shot it major until 9MM was outlawed for major. It was most accurate at around 1432fps with a 130gr .38super bullet (.356). That was a PF of 186 ( when PF was 175 for major ) The cartridge was loaded with the bullet as far out as possible with that particular gun. Used small rifle primers and 4756. unfortunately, that was a while back and I don't remember the charge weight. Was loaded on a Dillon 1000 by Tommy Weston, who was Area 4 Director at that time.

Flexmoney Posted February 16, 2012 Share Posted February 16, 2012 BTW I'm torn on what comp, either Carver Major or SJC Major. I can't comment of those comps from much direct experience, but one of those guys has a shooting background that is mostly USPSA and the other was more GSSF'centric.

CocoBolo Posted February 17, 2012 Share Posted February 17, 2012 You're loading short (compared to some other platforms.) I'd use the slowest powders (and the shortest bullets) available just to keep the pressure down as much as possible. I'd suggest N105 (yes you can make major with it in 9mm) 3n38, AA7. Let's talk OAL, with AA#7, 10gr with 124gr MTG CMJ, I kept cranking down on the seating die and measuring trying to get to my normal 1.165, well it never happened. After a while I put a case with no powder in it and the thing was 1.120, so I ran another one and watched carefully as it moved to the crimp station it grew, no matter what it came out 1.180. This was a problem since my gun had a short hole in it, so I had to cure that with a Manson Head Space reamer, opened it up to 1.185. Not sure if a Glock will even take that in the mag. N105 I ran in 38SC with 115gr and had issues with the OAL growing on a hot day. 3N38 will likely be similar. You will also encounter the dreaded powder sling with these very full cases. Is it worth it, won't know till you try it. Every gun is a bit different. There is no such thing as a safe 9 major round, if there was it would be in the load books. I tend to think of them as less dangerous at a longer OAL, I run SPP mostly magnums, lite it up. I've tried about everthing except N105 and at major they all start to flatten the edges of the primer. When you start to see no corner well that it definately not working. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted February 17, 2012 Share Posted February 17, 2012 Hello: Guys he has to load short--like 1.140" OAL short. I was using HS-6 and Auto Comp with the Glock 17 I built to try open. I was also using 115 grain Montana Gold JHP. I tried 2 different comps, the Jager and the Lone Wolf. The Jager shot flatter but the Lone Wolf was softer. I liked the Jager better. I also liked the HS-6 better since it was softer also. I am not sure the other powders listed would work with that short of OAL.

al503 Posted February 17, 2012 Share Posted February 17, 2012 Let's talk OAL, with AA#7, 10gr with 124gr MTG CMJ, I kept cranking down on the seating die and measuring trying to get to my normal 1.165, well it never happened. I just loaded up 26 rounds: 10 grains of AA7 with a 124 grain MG FMJ (I don't have any CMJ but would think their length is similar.) I measured ten of the middle rounds (I never measure the first or last 8 for OAL as all 8 stations aren't full on the 1050.) I loaded for 1.135 and got a range of 1.134 to 1.138" using mixed brass. I'll measure them again in the AM to see if they grow. You can also use a shorter bullet. The 124 FMJ MG was .584" while my 125 JHP Zero was .565" Just using a different bullet can net you down almost .02" After a while I put a case with no powder in it and the thing was 1.120, so I ran another one and watched carefully as it moved to the crimp station it grew, no matter what it came out 1.180. Don't know what to tell you here unless you have a typo. If you put a round at 1.12" next to one that is 1.18", that should scare you. If you're saying that it's growing that much without any powder, with all due respect, you need review your reloading procedure. You will also encounter the dreaded powder sling with these very full cases. Is it worth it, won't know till you try it. Every gun is a bit different. AA7 is easy to load as its so dense. At 10 grains, you have a shade over .2" of empty case. You do have to go very slow with N105 and 3n38. There is no such thing as a safe 9 major round, if there was it would be in the load books. I tend to think of them as less dangerous at a longer OAL, I run SPP mostly magnums, lite it up. I've tried about everthing except N105 and at major they all start to flatten the edges of the primer. When you start to see no corner well that it definately not working. Most of the info I've seen have the OAL's on the shorter side. I think if you load as long as you can with the slowest powders, you might be close one way or the other. If you're loading with a faster powder and/or shorter OAL, you're definitely past SAAMI specs. Link to comment Share on other sites More sharing options...

I have also used HP-38 which is Ok But is very Dirty. Link to comment Share on other sites More sharing options...
