vihta vuori in 9 mm

I'd like to try this at around a 130 power factor, for any bullet weight. Right now, it looks like their web site is being re-done, but as I recall, the data they listed was much hotter.

Can you share your 9mm loads in the vicininty of 130 PF?

Also, if anyone can tell me how to fit the new style forum threads onto my screen (they've grown), I'd appreciate it.

Many thanks,

2cats

I've been using 6.2grs VV3N37 behind a Raineer 115 RN for a pf of 139. The VV powders are very nice after using bullseye and unique. Hardly have to clean the gun! :D

There was a thread on Matt Burkett's board talking about an annoying secondary ignition with 3N37. I only shoot outdoors and have had no problem.

FWIW, I used 3N37 because it was all the local shop had...Probably would try N340 for the 115gr if it were available.

I shoot VV 320 3.2 grains for about 132 pf. Using a 147gr West Coast Gold. Check the thread titled Glock 34 loads. Steve Anderson lists some VV 310 loads using a zero 147 gr JHP.

The 310 loads have noticably less flip and faster sight recovery than 320 the same pf with 147 gr bullets.

The difference is similar to Universal clays vs. Clays.

310 uses about a .10 grain less to make factor.

VV N330 is the mother of all 9mm Luger powders. I currently shoot it under a 115 JHP at around 135 PF from a G17 (that's only because I developed it to make 125+ PF) from an itty bitty barrel G26.

I really like it with 147s, too.

Here you are my recipes (originally developed for 9x21 mm, silly italian version of 9x19):

The below loads were tested in a short barrel (SW 6904, 3.5" barrel)

123 grs lead TC-BB:

4.4 grs Vihtavuori N320 - 1.120" O.A.L. - 135 P.F.

4.9 grs Vihtavuori N340 - 1.120" O.A.L. - 131 P.F.

128 grs lead CN-BB:

4.1 grs Vihtavuori N320 - 1.160" O.A.L. - 130 P.F.

The below loads were tested in a 5" barrel (Tanfoglio T95)

137 grs lead RN-BB:

3.5 grs Vihtavuori N320 - 1.165" O.A.L. - 132 P.F.

4.2 grs Vihtavuori N340 - 1.165" O.A.L. - 132 P.F.

I have completed extensive work with N-310 & 147 grain jacketed & TMJ/plated bullets. As Steven Anderson suggests, this is an outstanding load which obviously works well for Mr. Burkett. How good is this load?

-At the 2004 S&W Winter Nationals (IDPA), second place in SSP was Phil Strader shooting a box stock Glock 17. He used the N-310 load with a Zero 147 over 3.2 grns of N-310 @ 1.150" OAL & once fired Hirtenberger L7A1 cases. I know this because I loaded that ammo personally.

-Both of the New York rounds of GSSF in 2004 (Am. Civ. and (1) Competition Division) were won by my team mate on Team Shooters Paradise GSSF. He used the same load as above though with mixed cases. THe bullets used were also Zero JHPs which yield supperior accuracy.

HOWEVER, this load WILL generate +p+ pressures. If you run this on the internal ballistics calculator "Quickload", it is predicted to be over 42,000 PSI - which is generally acknowledged to be more than 5% above actual pressures. However, the pressures generated are still considerable.

You should employ the safety precautions of using a Lee brand "U" or undersize die to prevent the possibility of setback. At a minimum, used the Lee brand Factory Crimp die for the same reason. If you are shooting a G34, you can back down to 3.0 or 3.1 grns.

You can obtain further extensive information on this load by doing a search on my username on GlockTalk.com; "Carlitos" or by searching my posts here on be.com. Good luck 2cats.

4.1 N320 with Zero 125 JHP OAL 1.12 = 1085 FPS

4.1 N320 with Berry 124 RN OAL 1.14= 1035 FPS

4.1 N320 with Berry 124 FP OAL 1.07 = 1050 FPS

4.9 N330 With Zero 125 JHP OAL 1.12 = 1135 FPS

I have heard you have to be very careful using N310 since it is very sensitive just a 0.1 more will gain you at least 50 fps more in velocity. Most of the competitors I know are either using 3n37 or N320 in 9mm. 124 gr and 147 gr are more popular in my area than 115 gr. Most say that use the 147 gr jacketed bullets from Montana Gold are very soft using the VV 3n37. As with any reloading, you must be careful on load data - also - depends on barrel lengths. Also, you must at least use a load that will first cycle the gun properly besides getting to the PF needed. Most people shooting GLOCKS have harder trouble getting right near 125 PF without changing springs - etc.

What does it say about a 132 pf N320 load? How 'bout 138 pf?

I've replicated my 320/147 load in quickload. 3.3 grs is 25942 psi at 1.157 oal and 133 pf

3.5 gives 29460 and a pf of 138.3

3.8 grains is 35429 psi Over Sammi max which QL has at 34083psi

I have played around with different 147 grain bullets and barrel lengths until I found something that roughly matched what I saw in my 34. In other words, my model behavior is usually very close predictor of actual in my gun. I can not speak to the pressure, but if I would go to 3.5 I would get 138pf, that I'm pretty confident. Your gun will be different but this is ballpark.

4.4gr of VV-N340 under a Berry's 124gr. flat point bullet gave an average of 1104 fps with an extreme spread of 21fps in my CZ 85. It was clean and also was the most accurate powder for the Berry's plated bullets.

On the CZ Forum, Angus Hobdell said that he changed from N310 to N350 under his Rose 124gr bullets and saw his group sizes at 25yds cut in half at the same PF.

My 2 cents.

HTR,

Thanks for the info. I've also settled on 3.3-gr. N320 as my 147-gr. Montana Gold load, though I'm running it at 1.155". Good to know the pressures are so reasonable. Was that 133 pf out of a Glock 34?

HTR,

Since you have access - and know how to use - Quickload, could you give me pressures on both these loads, all in one posting?

Montana Gold 147-gr. CMJ, 3.1-gr. N310, OAL 1.155"

Montana Gold 147-gr. CMJ, 3.3-gr. N320, OAL 1.155"

I've also got a question on a couple of .45 ACP loads with N310, but don't have the exact load data to hand at the moment. Hope I'm not being too selfish of you time and efforts.

The bullet selection in QL is one of the more limited portions.

In the model I have of my g-34 I use a speer gold dot, because it matches well with with I observe from my velocites and using a reasonable barrel length for the model.

Hornady 147 RN Enc/FMJ

310 - 46981 psi

320 - 33976 psi

Hornady 147 XTP

310 - 38532 psi

320 - 27820 psi

Speer 147 Gold Dot

310 - 36476 psi

320 - 26134 psi

Speer 147 TMJ

310 - 38202 psi

320 - 27378 psi

All of these were modeled using 1.155 oal, 310 was 3.1 grs, and 320 was 3.3 grs

I think my version of QL is 1 or 2 updates out of date, but I still trust it for my data

DT shoot me an email with the 45 loads, or post them here.

230 jacked .451 - 16000-20000 depending on the choices

most were 18-20

I poste dit elsewher but try VV N350 man that groups fantasic.

I gave up on what i feels like now I am searching or the group.

I feel if you fo your bit and the sight are "near" the middle the size of the group then help to keep it in the A.

I want to drive a 124 fmj around 1075 fps from my Glock 19.

What load and OAL would you suggest for VV330?

Or for any other VV powder?

The book load of 1.142" OAL with the starting load of 4.8 gr of N330 should be a hair faster than that.

You can download the data at the Lapua/VV web site. N320 might be better at your target velocity. N340 and the slower powders would be better if you wanted to pump up the velocity.
