IHMSA15151 Posted January 25, 2016 Share Posted January 25, 2016 I'm still waiting on my STI DVC open gun in 9mm major so to help pass the time I thought I would get some loading in. I plan on using a 125 gr. bullet and VV N350. I chose that powder as it was the only one available for purchase of the several I had read about as being used for 9 major. Researching this site I have determined that I should start at 6.0 grs. and slowly work up using the chronograph and watching for pressure signs and might end up as high as 7.0-7.5. Well, I drop 6.0 grs. into a 9mm case and it's pretty full. With 7.0 it just about fills it up. I know I will most likely set my overall length longer than normal, but until I get the pistol in hand I don't really know what bullet depth will work. So my question is, is this case volume the norm for 9 major loads? I was able to compress the powder for the most part, but would like to know if that's what others have experienced.

kneelingatlas Posted January 25, 2016 Share Posted January 25, 2016 I fill a case with 9.4gr of SP2 then cram a 115 on top, welcome to the dark side Link to comment Share on other sites More sharing options...
Flatland Shooter Posted January 25, 2016 Share Posted January 25, 2016 (edited) I've been loading 9 Major with VV N-350 for years. I also load what has been termed as "stupid" long. AOL = 1.195" using MG 124 gr JHP bullets. Due to several popple holes, I use a little more powder than you have listed as your max without any problem and its definitely a compressed load. (That's measured with my scales,) Shooting this load a chronograph is definitely your friend. I load to 171.5 PF (1372 fps) and have had zero problems. Gone are the days of shooting that nasty dirty HS-6. No split cases or funny looking primers. (I usually lose my brass before I can wear it out.) (Just a little side note: along with lowering pressure, I like to load my major loads long so that they do not fit in my Glock magazines. I'm concerned it would not be a good combination.)

GrumpyOne Posted January 25, 2016 Share Posted January 25, 2016 Not 9mm, but I load 10.5 of N105 in a 38 super case...maybe 1/16th of an inch from spilling over....and then cram a 115jhp on top of it... Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted January 25, 2016 Share Posted January 25, 2016 I used to seat 115 gr MG JHP's to 1.175" because of all the powder in the case - but I did get 1-2 bullets fell out of the case during the cycling process - spilling powder in the gun and the bullet falling out when I racked the slide. Possible to load really long - but you have to be very careful and size the case tight. Link to comment Share on other sites More sharing options...
IHMSA15151 Posted January 26, 2016 Author Share Posted January 26, 2016 Thanks guys. I was able to seat the bullet to 1.170 without any issues. I loaded a few at 6.0, 6.5 & 7.0 to run over the chrono. Now it's back to waiting. Link to comment Share on other sites More sharing options...
accu9 Posted January 26, 2016 Share Posted January 26, 2016 No need to fear compression loading 9 major. All of my 3N37 and 3N38 loads are compressed albeit those are slower powders. Link to comment Share on other sites More sharing options...
shooterclay Posted January 26, 2016 Share Posted January 26, 2016 Just started loading 7.1 autocomp 124g MG JHP 1.16OAL was producing 1438fps with range brass. Haven't seen any problems,....yet. Link to comment Share on other sites More sharing options...

All VIT powders are clean. I've been using HS6 for years in Open. Not even nasty dirty. What does HS6 have to do with split cases? Link to comment Share on other sites More sharing options...
