I just got that same exact response from Dave Campbell.

I also queried the HS-7 rumour but have not gotten a reply on that yet.

Regards,

Just talked to Chris at Hodgdon

HS-6---no plans to discontinue.

HS-7 ---discontinued about a year ago. Still some out there, but when it's gone it's gone.

Hodgdon is now carrying VihtaVouri powders. They will be available through regular

Hodgdon distribution channels.

N310, N320, N340, N350, 3N37, 3N38, N105 were all mentioned.

I mentioned that a shipload of SP-2 would probably be a saleable item, and Chris

actually sounded interested. Have to wait and see on that one.

A little more data......

ALL loads loaded to 1.195", Zero 115 JHP, Federal Small Pistol primer, Winchester cases. Temp was low 50's. 15 feet from the chrono, bright sunny day.

8.1 Longshot, average velocity 1530, ES a little loose at 66 but plenty of room on the power factor since they are making 176. Good predictable vertical dot track. Primers show round edges with very little flattening and NO flow. Noise is a little extreme, but the powder is cheap, reliable and on the shelf everywhere around here.

Longshot will go to about 181 for me with the same components, then it starts coming back down in power factor and going WAY up in ES. It still doesn't show much pressure but it is obvious that it will not go any further.

N105, I think I found my steel load with 8.8 grains. Works out to be 150 PF, shoots great and is super soft. I worked it out all the way to a full case at 9.8 grains, average velocity was 1390 for 160 PF. There isn't a workable way to get any more in the case and still load progressively, too bad too because the dot track was really straight, very little dot rise, and softer shooting than anything else I have tried so far.

3n-37, 8.8 grains is 170 PF, extremely hot gun after just a few rounds but it feels good and shoots fantastic. 9.0 grains is 177 PF, a little brisk in recoil but feels good and shoots great.

Silhouette, my favorite so far, too bad I can't buy it locally. 8.8 makes 171.3 power factor, is really soft, a little less dot rise than Longshot, and the ES is fantastic at just 16 fps over 10 rounds. I am going to have to order a big can of it, it really is the best I have found so far.

HSMITH, Are those 115 grain loads?

im testing vv n350 right now...7.0 grains with a 124 at 1.150 was WAY major..

6.8 grains makes 170 pf in my gun...5.1 inch trubor 9x19.

Im using Win pistol primers now....as i cannot get my beloved federals.

Harmon, yes they are 115 Zero JHP. So far it is the only bullet I have worked with. I have two more powders to work up with them and then I move on to the 124/125's. I probably won't spend the time with the 124/125's that I did with the 115's, I put well over a thousand 115's over the chrono and into groups and frankly it was a lot like work....

Mine is a 5.4" KKM with a Bedell TI comp.

3n38, 8.8 grains 1.165 oal Precision delta FMJ and a winchester small pistol primer

this is a compressed load and slightly deforms the bullets nose but it shoots super soft and lots cleaner than HS6

average velocity is 1370 fps from my 5 inch gun

Tried out some loads on my new JL Hardy 4.5" Trubor

MG 124 JHP, WSR, 1.155 OAL, Federal Brass

HS-6

7.8 gr = 161 PF

8.1 gr = 169 PF

8.3 gr = 171 PF

True Blue

7.5 gr = 157 PF

3N38

8.5 gr = 169 PF

8.7 gr = 164 PF

9.0 gr = 167 PF

HS-6 is real dirty and harsher than 3N38. 3N38 was real nice. Very "dull" feel in the hand, less snappier than HS-6.

Additional Loads....(same gun/bullet/primer/OAL specs as previous post)

3N38 9.1 gr =170 PF

Longshot 7.3 gr = 166 PF

True Blue 8.0 gr = 166 PF (2nd Best Load - soft recoil, good dot movement)

VVN350 7.6 gr = 168 PF (Best Load for my gun - soft, dull recoil. very consistent dot movement.)

7625 7.2 gr = 171 PF (3rd Best Load - snappy and feels like 150 PF, erratic dot)

Off topic a bit, but I see you have experience with STI 9mm's.

I'm thinking of buying an STI 9mm very soon, and have some questions, as a newbie:

1. If I buy either the GrandMaster or the Trubore, who should I send it to for customization (

(better trigger & accuracy)? Or are they okay as comes from factory?

2. What are advantages/disadvantages of the GrandMaster vs the Trubore?

3. Are you happy with the STI 9mm?

Thanks for the help.

Jack

First,any information that I am about to disclose works in my gun and I am not responsible for the use of this info by anyone.

My gun is a 9mm Major STI shorty with a 4.5 inch barrel with a 3 port comp and 2 bleeder holes in the top of the barrel. It was built by Benny Hill.

The load that I have finally settled on that chrono's 1493avg. is with a 115gr. Star FMJ loaded in once fired FC cases using Federal Small Rifle Primers and 8.35grs of VV 3N37. The OAL is 1.155. I have not seen any signs of excessive pressure and in my gun it shoots very flat and is extremely accurate! This load is also used in my friends STI Competitor with a STI 9mm Trubor S-2 comp and is a couple of feet slower but performs just as well. I am using a 10lbs ISMI recoil spring in my gun and may try going to an 11.

Just finished setting up a 9mm major load for my G24 (converted from 40 to 9mm) with a stormlake 4-port barrel.

6.4gr Power Pistol

MGD 147gr-CMJ

WSPM

1.153 OAL

Pf = 170 (avg of 3 strings of 5 rounds each)

SD 15-18, ES 30-40

Going to 6.6gr gave a 175PF with similar SD and ES

I have used PP for 40 open for a number of years. I found it to be a very clean powder though a bit noisy. Just ask anyone who has RO'd me shooting a G22 with a 5-port hybrid barrel (some called it painful, but I never noticed :devil: ).

The 9mm load felt nice a soft with the (Jpoint on slide) dot tracking up/down very consistently. OAL is definitely a lot shorter than used for 1911 style guns due to feeding issues with Glock mags. The MGD bullets have a nice round nose on them which makes them feed very nice through the gun.

I know 4756 is bulky and not a suitable choice for 9 major, but I had to try it also. All loads with MG 124 JHPs, WSR primers,once-fired mixed brass (WIN, FED, R-P, Speer), OAL 1.175". Out of SV IMM Open 4.5" AET barrel 5-port comp w/2 holes on top. Shot these @ 55 degrees F.

Can make major if it's IPSC 160 PF, but would be a pain in the a.. to load as I had to go really slow to not dump any powder from station to station. I think that's why I was getting high ES in the 7.x loads I did. Had to really slow down during reloading once you get to 7.8+ range. And the last 2 loads (7.8 and 8.0) were compressed to say the least, the OAL was 1.180" on those. That's as far as the bullet would go with that much powder in the case. But all of the primers still looked rounder, no flattening. I think I will use 4756 for steel loads.

Hi,

I'm fairly new to reloading and brand new to major 9.

I just got a new STI Trubor in 9x19. This is my first batch

of handloads for the gun.

Ramshot Silhouette, 124 gr Montana Gold JHP, Winchester

White Box once fired brass, CCI Small Rifle primers

1.130 OAL, 70 degrees.

Chg avg hi lo SD ES AvgPF HiPF LoPF

6.6 1243 1256 1229 11 27 154 156 152

6.8 1282 1297 1265 12 32 159 161 157

7.0 1299 1308 1278 9 30 161 162 158

7.2 1318 1328 1295 11 33 163 165 161

7.4 1354 1369 1338 13 31 168 170 166

7.6 1380 1399 1364 11 35 171 173 169

7.8 1400 1412 1387 8 25 174 175 172

The picture shows the fired brass, with each row corresponding

to a particular powder charge (6.6 gr at the hinge, progressing

up to 7.8 gr in the row next to the unfired rounds)

Even the starting charge shows flattened primers and primer

flow. Should I be concerned with any of these loads? If so,

what should I do next? Try loading longer OAL?

Thanks in advance.

At the least, you need an extended firing pin... that primer shear is going to cause failures to fire, eventually, when the metal sheared off in the FP tunnel clogs it up sufficiently...

Try loading longer OAL?

With the MG 124 jhp, you should be able to go to at least 1.165 without issue. I'd try another batch at 1.165 to 1.17. I don't think it'll make your pressure issue go away but it will certainly help.

I tried WSF in SV IMM Open pistol, 5-port comp with 2 poppel holes. All loads using MG 121 IFPs, 1.175~1.180" OAL, Speer once-fired brass and Fed small pistol primers. I used my Silhoutte match load to make sure chrono was working OK, 124 MG JHPs, OAL, brass, and primers the same as WSF load.

I am going to bump it to 7.4~7.5 range and try to get to 170PF for a little bit more cushion for matches with chrono. I weighed the MG 121 IFPs and they actually come in around 121.6~121.7. Primers look good and no unburned powder like Silhoutte. It still get c-more lense dirty about as much as Silhoutte does however.

Added 7.5gr. load data.

WSF 7.5gr

The True Blue is a bit denser than the Silhouette at the same charge, and a bit faster, too. Both powders are dense enough to be good for fast progressive loading.
