[diehli]

Groovy... thanks for the info!

How do the different powders feel to you? What kinda setup are you running? Whose comp? Barrel ports? Recoilmaster or standard guide rod?

[Alan Meek]

Cullen,

Details on the gun

Caspian Hi-cap
Commander Slide Swooped and lightened to 9.5ozs stripped
Bar-sto Barrel 9x19 Actual Length 4.5"
Briley Titanium Quad Comp
10# Recoil Spring
Extreme Engineering Warp Speed set
Need to double check Mainspring. I'm thinking 17#
C-More Serendipity
EGW Magwell

I am actually liking the 7.0 -7.2 grains of N350 fell the best of all the loads that I have shot for an extended session gun tracks good dot never leaves the lens.

9x19 Major = Porno9 as it is Hard-Core

Alan,
Great work and thanks for sharing. Keep 'em coming.

[Robert Snyder]

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.

[Kingman]

Have to give him that one. His gun tracks alot flatter than my super.

[NMinzghor]

Have any of you guys tried Ramshot Silhouette vs True Blue? I'm using 7.65gr with MG 124 JHP @ 1.190 with WSR primers in my 9mm Shorty with 4 port comp and 2 snort holes but it is a bit violent @ 168PF. I'm thinking of trying True Blue. Be interested in hearing from someone who has tried both.
Thanks,
Nick

[GeneralChang]

Is it safe to say that all 9mm major loads will be compressed? Does anyone know what the case capacity of a 9mm is?

[Alan Meek]

Actually True Blue seems to have the best density leaving a good .25" to seat the bullet. This is with 8.0 grs.

[Little Bill]

True Blue and SP2 are not compressed loads. Most other viable powders are compressed, at least a little, and in some loads, compressed alot.

[RC1]

Little Bill,
I noticed that you are shooting a Hardy 9mm shorty, as I am.
How do you like the True Blue in it? I have been using primarily 3n38 and I like it accept for it being expensive and difficult to load. I have tried the True blue, on and off for the last few months, and so far it seems to work pretty well. The jury is still out on which one shoots the flattest and is the most accurate.
I would appreciate your input.
Thanks
Rick

[NMinzghor]

I have not had to compress the powder with Sihlouette, but I have been seating at 1.200. I guess I'll give True Blue a whirl. I'm shooting a Hardy upper as many of you are it sounds. Why do you guys load so short?

[Little Bill]

I really like True Blue, and I do prefer it to 3n38, regardless of price. I ran out of SP2 before I was able to do any comparison, but I think TB is very similar feeling.

I think that 3n38 makes too much gas, as I feel the gun tracks weird and I get more lateral dot movement with it. The TB gives me very predictable up/down movement only. The dot moves to the top of the glass or so and back. (Depending on my grip)

The TB also loads alot better than 3n38. TB is very fine, like SP2, and because the load is not compressed, my OALs are much more consistent. I have my press set at 1.150, and with TB they run from 1.152-1.149 like a clock. With 3n38, the OALs get strange because of how compressed (crushed) the load is, at least in my opinion. (1.148-1.160) The loads / gun shoot better than me, so the accuracy is a wash.

At Area 3, (which totally kicked my a$$ - I got 3rd B-class ), my load went 1361, 1350, 1341, 1347, giving me 168pf. (On my Pact MIV chrono at home the load averaged 1365fps)

IN MY GUN, USING MY PRESS / SCALE, for my match load, I am dropping 8.1 TB @ 1.150 with once-fired Fed Nickel +P+ brass, Zero 125 JHP, and WSR primers. The primers are FLAT, so please work up your load slowly and carefully.

I load short because thats what JL said to do. The STI mags / spacers will bind at about 1.165.

I like talking to Joey, because he always reminds me to stop tinkering with twinkie parts and twinkie loads, and just shoot the damn thing!

[MasterLefty]

Does anyone know what the case capacity of a 9mm is?

My ballistic program list the case capacity at 16 gr of H2O.

If I get out the the reloading room this evening, I will check a couple of different head stamps.

Kenny

[Newguy]

Thanks to Caspian-9major for the advice re: Tru Blu and for giving me a starting point. The powder meters well, is consistent and leaves enough room in the case to minimize spills. My chrono results are obviously different from Caspian and Little Bill since we're shooting two different guns and using different chronos.

Gun: STI 5" barrel, STI S-2 comp, NO barrel holes, Limcat XL fp

Tru Blu powder, WSR primers, 9mm range brass, 124 gr. MG JHP.

7.7 gr. TB, OAL=1.165 (1375 fps) @ a 170.5 pf.
7.5 gr. TB, OAL=1.65 (1356 fps) @ a 168.1 pf

[Little Bill]

I would be curious to see how different the 5" gun feels due to the reduced charge / reduced gas. Newguy, is your gun a Trubor or a screw on S-2 comp on a 5" barrel?

[Newguy]

Bill, it's a screw-on S-2 comp on a 5" barrel.

I don't know how to compare it to other guns since I'm new to open. I have shot a 9mm STI shorty, which I found to harsh and uncomfortable to shoot.

What kind of gun (specs) are you loading TB for? My primers were VERY flat at 7.7 gr. (OAL=1.145) and I can't imagine loading 8.1 grs to make a 168 pf. There's a pretty big difference between your loads and mine (which are closer to Caspian's chronoed loads)..

[NMinzghor]

Surprised to hear that you have to use that much powder loading that short. Like I mentioned earlier with Sihoulette I am at 7.65 loaded at 1.200 OAL with no signs of pressure at all. But it is very snappy to say the least and I don't think it works the comp that well in my shorty JL upper. Like new guy I am new to open as well. Just made master in Limited but these open guns are finnicky. Thanks for all the help...hoping to have a good load worked out soon. Anybody tried using TB and loading long like at 1.190 or 1.200?

Little Bill if you are shooting a JL gun what charge are you using?

[Little Bill]

Newguy-
If you have a 5" gun, with a screw-on comp, (not cone or trubor) that gives you an actual barrel length of 5.5". That could account for some of the velocity difference to my 4.5".

In my opinion, , my shorty is softer than 80% of the supers I have shot, and is just as flat. I don't know why, but most agree with me.

For my load info, look up a few posts in this thread....

[NMinzghor]

I'm going to load up some TB this week and will try loading some long as well for the guys using SV mags. I'll post my results.

[Harmon]

Longshot should be renamed to LOUDSHOT
I ran out of HS6 in my nine and decided to try longshot...even with minor power loads in production glock(5.5 grains, 115 MG fmj 1.15OAL) it was quite a bit louder.
Power pistol is about the only other powder i have tried that was as LOUD.

I can only imagine what a comp gun would be like with those powders....OUCH

anyone use power pistol in their open guns??

[Alan Meek]

Also Longshot has the ability to remove fillings. I shot a load in my .40 open a few years ago and the concussion was incredible. The RO actually complained. Of course my comp did not help as the three ports are tilted back 11 degrees.

[Kingman]

I am going to try some Longshot in both a normal open gun and a hybrid gun. Sorry RO's. Though it can't be any worse than the Winchester 540 I was running.

I was going to use TB but the deal I can get on Longshot makes it worth at least trying.

[Alan Meek]

Kingman, I think you will find otherwise in the comparision between 540 and longshot...
