jellyb Posted January 13, 2016 Share Posted January 13, 2016 (edited) What is your OAL running major 9 out of an STI or SV? Using STI mags with SC spacers. I run 1.165 PD jhp's and occasionally get stuck in the magazine. What is the shortest I should or can load to? I am thinking about trying 1.160. All input is much appreciated. Thanks, Jellyb Edited January 13, 2016 by jellyb Link to comment Share on other sites More sharing options...
al503 Posted January 13, 2016 Share Posted January 13, 2016 I think you should load as long as your chamber and mags allow as long as you have no issues with setback. That'll help keep the initial pressure spike down as much as possible. I run SV mags. 125 zeros at 1.19" and 1.2" with 124 MG's. With bulkier powders, IE compressed load, I load them slightly longer.

Slostang Posted January 13, 2016 Share Posted January 13, 2016 (edited) I run mine at 1.16. MBX mags mainly but also works 100% in my one Sti mag with spacer. Edited January 13, 2016 by Slostang Link to comment Share on other sites More sharing options...

Sarge Posted January 13, 2016 Share Posted January 13, 2016 Check your mags. Make sure to polish inside. I run 1.168 with spacers and there is plenty of room. Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted January 13, 2016 Share Posted January 13, 2016 I'm running 124 RMR HP at 1.2" I've never heard of a 9mm Major at 1.2"??? You sure this isn't a .38 super, or 1.162"? Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted January 13, 2016 Share Posted January 13, 2016 Using STI mags with SC spacers. I run 1.165 PD jhp's and occasionally get stuck in the magazine. I use STI mags with spacers and have loaded out to 1.175" without any problem - not sure why you'd have them get "stuck in the mag"? Could it be the mag? To answer your question, though, I run 124 gr MG JHP's at 1.165", but have run them as low as 1.145" and they work fine - so you can shorten them up quite a bit as long as you check the chrono and work up slowly after you drop a few .1 grains of powder - shouldn't be a problem, but I'd look at the mags first.

Open1215 Posted January 13, 2016 Share Posted January 13, 2016 I just loaded some N 105 at 1.20 to see if it can be done... I'm having nose dives in my 140mm so I hope this fixes it! I'm at my press now. Link to comment Share on other sites More sharing options...

I'm at my press now. When I loaded to 1.18" I had a bullet separate from the case as it loaded into the chamber -dropping powder and the bullet. You might want to push and pull a few of those 1.2" ers and make sure you can't pull the bullets out by hand .... Link to comment Share on other sites More sharing options...

You might want to push and pull a few of those 1.2" ers and make sure you can't pull the bullets out by hand .... It depends on the length/weight of the bullet. With 124 gr MG JHP's, 1.2" isn't an issue. With a shorter bullet like a 115 or 121, you might have some issues at that length. Link to comment Share on other sites More sharing options...
Open1215 Posted January 14, 2016 Share Posted January 14, 2016 I chambered many of them checking mag function, I didn't have any issues. They are 115g but they don't seem to be touching the rifling enough to stick. Link to comment Share on other sites More sharing options...
Novock Posted January 14, 2016 Share Posted January 14, 2016 I run a different platform, but run 9mm major at 1.155 with 115's and HS6 without issue. My magazines limit my oal more than you guys with steel guns, but 3500 rounds so far through my glock open gun without issue with this oal at 170-171pf.

Your asking for trouble. N105 will not make major. A 9 case will barely hold a projectile at 1.185. You are really compressing the powder and the powder will PUSH the bullet higher in the case after they are loaded. Even if you could do it-most 9 chambers will not allow a 9 loaded that long. I bet you can pull the bullet out of the case with your fingers once loaded. Not good! Link to comment Share on other sites More sharing options...
Open1215 Posted January 14, 2016 Share Posted January 14, 2016 So far no issues. I don't think I'll make major with N105 but if I can get close it will be fun for steel. I'm picking up some spacers now anyway. I have to fix my nosedive issue. Link to comment Share on other sites More sharing options...
theWacoKid Posted January 14, 2016 Share Posted January 14, 2016 I started tinkering with a N105 9mm load and I was so far from major with my starting load I didn't have urgency to pursue it. The rounds I tested were loaded to 1.195" with 124 grain MG's. They functioned. I think the key is to completely minimize the flare. I flared so little that it required guiding the bullet into the seating die with my hand and no crimp was needed to get the neck to final dimensions or pass a case gauge. I've definitely seen some flare so much that seating that long would have nearly no neck tension and I imagine that would be bad. The bulk of my 9mm major loads have been with HS-6 in the 1.165" range with 115's and 1.175" range with 124's. No issues from those lengths thus far. Standard SVI Ultimatch barrel.

Open1215 Posted January 14, 2016 Share Posted January 14, 2016 Ya my go to is hs6 under a 115. I really like it. I read someone had success with 105 but I don't see it. It will be fun for steel but I can't see getting enough in it. Even if I could get 9.5g to compress and seat, idk if it would hit major. What did your data get to?

al503 Posted January 14, 2016 Share Posted January 14, 2016 Sorry for the thread drift but n105 will make major with a 124/125 grain bullet. I did it with a shorty with 4 poppleholes (Brazos Pro SX) and it was 169+ PF. I could have gotten a couple more tenths in the case, also. If you don't have bbl holes and/or longer bbl, you won't have any issues making major. Link to comment Share on other sites More sharing options...
Open1215 Posted January 14, 2016 Share Posted January 14, 2016 Yes sorry for the drift. I'm having nosedive issues myself, I'm debating going spacers or not. Thankfully a friend is letting me use some of his to be sure it runs in my gun. Go from there. Link to comment Share on other sites More sharing options...

A long time ago....hs smith did a lot of testing with n105.... He posted 5.4 KKM barrel at 169 PF with 10.8 gn, 115 at 1.195 OAL. With a 115 JHP you have more room in the case. I remember he noted that the cases would not grip the bullet enough to be reliable. The bullet would shift in the mag etc. Link to comment Share on other sites More sharing options...
