Hi,

I'm thinking about loading some 180gr HP's with some n105. My velocity goal from a stock G20 is around 1200 fps.

I saw a bunch of n105 data earlier in this thread, how many of these loads are compressed? At 1.260" QuickLoad seems to think you can only get 9.6 grains in a case without compressing. I noticed some of the loads posted above are in the 12+ grains category...

I'm trying to decide between n105 and 3n37 for a starting powder.

Thanks,

Alan

Vihta Vuori Powder Data

I tried to use 105 for my 10mm and didn't care for it. I think the VV site specs are WAY off their published velocity. I don't have a chrono but the only difference I could feel was slide velocity and dings in the cases and flattened primers. I just used my 105 in my .41 Mag yesterday with a Hornaday 180GR XTP with 14.6 gr. I think it was about 1400 fps. The Lee manual listed a max of 15.1c is 1480fps. I thought 14.6 was plenty.

If you have room in your case with N340 and would like a little softer feeling recoil, you might try a pound of N350 (quite possibly the world's most FORGIVING powder)and go nuts. The beauty of N350 is that it will only burn what it can in the barrel, the rest is in the form of a flame ball coming out the front of the gun.<P>
Make sure you're increasing your spring rate in the G20...recoil is about to get ugly.<P>
If you're going for speed, I've always had good luck with AA#7. Once you get the pressures up, it burns clean. <P>
Double check me sometime, but I think that if you fill both a 9x25 and a 357sig to the top, the sig will hold .3gr more than the 9X25. I think it's due to the internal web thickness.<P>
Lemme know how this all works out for you.

I've got a few pounds of N350, CCI 300 (large pistol) primers, Starline 10mm brass and 180 grain Oregon Trail Laser Cast bullets. Any recommendations on powder charges? I'd like to work up to full 10mm loads. Thanks in advance!

10 mm

Hi Doc, I used Oregon Trail bullets and they smoke a lot when fired. The barrel was also dirty. I use Rainier 180 gr. FP, not RNFP. 11.0 gr of AA-7, 1.250 OAL, WLP. and a crimp of .421. This is a published load for 1200 fps. Semper Fi Doc!

Stationed at Quantico in '72... took care of many U.S. Marines coming back from 'nam - trauma/surgery. You guys are great!

I've got some Speer 180 gr. TMJ (value pkg) bullets too. In "The Complete Reloading Manual for the 10mm and .40S&W", powder burning rate chart, in order of burn rates, N350 is #32 and AA#7 is #34 (suggesting N350 is a little faster). Could I substitute AA#7 for N350? (I'm shooting a G20 with a Lone Wolf fully supported barrel.) I got the N350 for .40S&W reloads, but like shooting the 10mm more. Appreciate any advice/input. Semper Fi!

Vihta Vuori Powder Data

Hi Doc. I don't see why not. I would use 1.260 OAL, and start your loads at 9.6. I would check Lee's Second Edition to see if they list a comparable bullet combo with a jacketed bullet. You will use more powder with jacketed. If you have feeding problems, shorten to 1.250. Corpsman took good care of me at Chu Lai, Great Lakes, and the Naval Hospital at Beaufort. My son was born at Beaufort Naval Hospital.

The 2009 VihtaVuori Powder Manual:

"N350 - This is the slowest burning N300 series handgun powder,
which can usually be used instead of Accurate No.7, IMR Hi-
Skor 800-X and Alliant Blue Dot. Appropriate choice for many
powerful handgun loads, for example in calibers 9 mm Luger,
10 mm AUTO and .45 ACP."

In case anyone ever shows up on this forum again...

I have several Glock 20 barrel configurations....most are ported.

In reading seems like the porting likes the lighter faster bullets rather than the heavy slower ones...

So I was looking for data on the 135 gr bullet.

My barrels are:

G20 with 5.2" with 2 external ports and 2 internal "c" ports.

G20 With a Tactical slide and 4 internal ports.

G29 with 2 external ports...

I have several classes comming up where follow up shots are really important. Did well last time with the stock Glock 20c, butl not starting to build something faster/better.

All 10 rounds were in a 3 inch diameter circle from 25 yards using open sights and a rest on barrel side of gun only.

G-20 with stock length KKM barrel
Starline Brass
CCI 300 primers (do not use mag primers with this powder).
OAL 1.250

Please Note: do not try to fire these loads in a stock Glock barrel. 9.3 was max load for the stock Glock barrel. See bottom of page for further information.




9.5 grains:
GROUP #6
1) 1163.0 14.8
2) 1160.0 11.8
3) 1152.0 3.8
4) 1134.0 -14.2
5) 1131.0 -17.2 ƒ
6) 1141.0 -7.2
7) 1152.0 3.8
8) 1146.0 -2.2
9) 1149.0 0.8
10) 1154.0 5.8
High: 1163.0
Low: 1131.0
E.S.: 32.0
Ave.: 1148.2
S.D.: 10.4
95%: 8.0




10 grains:
GROUP #7
1) 1196.0 11.4 ƒ
2) 1182.0 -2.6
3) 1194.0 9.4
4) 1192.0 7.4
5) 1174.0 -10.6
6) 1182.0 -2.6
7) 1183.0 -1.6
8) 1182.0 -2.6
9) 1184.0 -0.6
10) 1178.0 -6.6
High: 1196.0
Low: 1174.0
E.S.: 22.0
Ave.: 1184.6
S.D.: 7.0
95%: 6.0





Maximum safe load with stock Glock barrel was 9.3 grains of VV 3N38 at 65 F OAT. This load produced only 1135 fps. 9.5 grains don't even try it with the stock Glock barrel. Very heavy smileys on all cases. I believe this powder was actually designed for lighter weight bullets in mind.

Maximum safe load using KKM barrel was 10.5 grains of VV 3N38 at 65 F OAT. This load produced 1221 fps with a SD of a low 4.2 I took the load as high as 10.8 but got light smileys on 75% of brass. 10.8 grains of VV 3N38 gave 1252 fps which matches DoubleTap Ammo; however, Mikes DT Ammo is running at much lower pressures and much safer.

I am learning that with the KKM aftermarket barrel with powders in this burn range, you can load 10% more powder which gives you approximately 110 fps more with same pressure signs as compared to the Glock stock barrel.


I can confirm your numbers data for VV3N38 using the 9.5gr and 10 gr using 200gr XTP. However tested the 9.5gr out of the stock barrel and 10gr out of an LWD stock length barrel.

Signs of pressure at 10gr but nothing serious.

Why does Vhit not post the correct data with their N105? 9gr pushing a 200gr XTP only yielded about 1050 FPS. They show 1162 with only 8.6gr. Something is not right.

Maybe it's different barrel length, barrel type, primers ...

Hi snair,

n320 is a bit slower that than n310. n320 is my "goto" powder for any sort of light load I want. I've used it in 45/70, 38 special, etc.

robert91922 - be very careful, VV doesn't show n105 loads for 45acp and n105 is very very slow.

Good luck,

Alan

ups, I misstyped it. It is a 10mm Glock 20 of course, NOT 45acp Glock21.
I even don't own anything in 45acp caliber.

alank2 - thanks for warning anyway

VV N105 & Winchester JHP 180gr - Part TWO

EDIT (10-22-2010): These measured data is ALL WRONG BECAUSE OF TOO SHORT DISTANCE BETWEEN CHRONO SCREENS!!! Look at my another post a little below
___________________________________
Here you are, finally I succeeded to load and measure the next generation of my 10mm babies:
- Glock 20 stock barrel
- recoil spring: DPM MS Glock20 3-spring system - http://www.dpmsystems.com/en/products/
- primers: CCI 300 LP
- powder: VV N105
- bullets: Winchester JHP 180gr
- brass: Starline (new)
- COAL: 1.260
- temperature: 54 F (12C)

Special thanks to: Mr. Jan S.M. - owner of "my" Dillon XL650 and Mr. Bostjan P. - owner of the range closest to my residence

load (grains) average (fps)
11,2..............1319
11,4..............1340
11,6..............1360
11,8..............1372
12,0..............1375
12,2..............1386

No signs of overpressure till 12,2gr, when third case out of 3 had a 10mm crack along in the middle, so I suppose 12,0gr would be maximum for this configuration. I was using 3 mags, only 1 round in each mag to prevent warming of next round in chamber while I'm writing down measured speed and taking a good look to a case just spent. I was using Acuna Brass Catcher, which caught almost all cases if I fixed it to sit properly on pistol rail after each shot -had only to pull it back 2 or 3 mm to fit.
On the lower edge of each case I found a scratch, probably caused by extractor.
And YES, I still have all my 10 fingers on

And here's some pictures:

Well, comparing this data with other similar loads from other reloaders (180gr/N105)... I am not sure anymore that these mine are correct. I will repeat measuring these loads with another chronograph and post it

I would do exactly that....2 things I notice:

1. Your primers are not what I would call "great". The flowing of the firing pin hole is not not normal.

2. The splitting of the cases indicates high pressure..

a. check your powder calibration again. (How did you weigh and meter your powder?)

b. check the distance between screens on the crono.

In looking at the 1st page of the reloading date here:

180 Remington FMJFP
New Winchester Brass
Rem 2 1/2 primers
COL 1.265"
~ 55F
9 or 10 shot strings on all barrels

12.5 N105
Gun/barrel Lo Hi ES Avg SD
G29 1249 1282 33 1266 9
G20 1330 1355 25 1339 7
1911 5" 1342 1380 38 1358 12
G20 Jarvis 6" 1388 1430 42 1412 16

It indicates in 4 different guns a load of 12.5 was working normal. Only difference is the Rem 2 1/2 primer vs a CCI 300. If you had been using CCI 350 it would explain the difference.

Since I have 200 rounds sitting here ready to load with VV 105, I am very interested in your conclusions.
