    Just received my first pound of VV 3N38 powder and will be working up loads in the G-20 using the 200gr. XTP bullet. Due to no real load data being available, an educated guess with aftermarket barrel will put my starting loads at 9.5 grains, then moving to 10, 10.5 and last group to be fired if pressure is still within limits will be 10.8 grains. Will post the data here as soon as I get these rounds through my chronograph. Looking to reach somewhere around 1225 fps.

    Here is the data using VV 3N38 and the 200 grain XTP Bullet. Anybody ever seen a handgun load with a 4.2 on standard deviation. That is great!!! This was the most accurate powder I have used yet. 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.

    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.

    Yes VV is the best so far for over the counter purchases. This will be my keeper load with the 200gr. XTP bullets. Load density was like 99% and this powder meters perfectly. What a great combo for the 10mm.

    I had the chance to shoot some of my reloads of a Chrono tonight, and I thought I might as well share the results with you. I've only loaded a couple of hundred rounds so far, so it may be that my powder charges aren't that precise, though I've tried to keep them constant.

    All of these are average for 4-5 shots (few errors from the Chrony):

    190gn Privi FMJ
    COL 1.255"
    Glock 20 stock barrel
    VithaVuori N105
    Winchester Large Pistol primers
    New Starline brass

    VVN105 - Avg FPS - StdDev

    11.0gn -- 1180 ----- 9
    11.3gn -- 1198 ---- 18
    11.6gn -- 1210 ----- 7
    11.9gn -- 1210 ----- 7
    12.5gn -- 1275 ---- 18

    My 'easy load' that I plan to use for standard class IPSC nicely met it's expectations:

    8.5gn ---- 914 ---- 39

    Which is PF 174, though the deviation is a bit high.

    I couldn't quite match the 240gn @ 1285fps my girlfriend is shooting though... ^8
     
  8. I tried some loads with n-110. It's abit to slow. But if someone have good ideas how to compress the load(not only bullet)it could be usefull.

    OK Gang, I've got the complete spectrum of Vihta Vouri N340 worked out for 10mm 155Gr FMJ - complete with graph!

    The following data was all chronyed in a single range session at 75 degres through a stock Glock 20 (4.6" barrel) with a Pact Mark IV. Bullets are all 155gr West Coast Truncated Cone, with COL of 1.260", primers are CCI. The data is based on 6-shot samples (throwing no data out as fliers).

    Here's a graph on the Grains vs. FPS, FPE, & PF:

    [​IMG]
    For some stinking reason the image won't embed - have to just link to it - sorry!

    At the low end, the slide on my G-20 still cycled reliably, but it's had over 20K rounds through it and the recoil spring is definitely ready for replacement. On the high end, I could definitely start to see the imprint of the firing pin channel in the primer, but they weren't noticeably flattening out yet and there was no sign of "smilies".

    Having said that: As always, the following Disclaimer applies to this reloading data (and any other you may find published here on GT, or anywhere!): "This worked in one person's gun, and might not work in yours. Start low and work up at your own risk!"

  10. Is that the highest you can achieve(1333 fps) using a 155 grainer? I'd assume you'd be able to push 'em to at least 1450 or even higher with your selected powder.

    When I played with 155 gr Hornady's using a few powders, I even considered the 1400 fps mark unimpressive.

    B-Bo,

    That's the highest I'd loaded up that day! I figured I'd have smilies at about 8.5gr and would never even shoot the 9.2gr, but that didn't happen.

    I need to go back and load up rounds from 9.2 to about 12.0 - and guessing the dreaded smilies will stop me somewhere around 10gr. ;f

    I'm hoping Santy Claus brings me an electronic powder dispenser so I can work up a similar "complete spectrum" for 180 gr bullets with N340, and both bullet weights for N350 and N105. Tedious work measuring each load by hand...

    kestrou
     
  12. Anybody have data for 165, 180 and 200 gr w/ 340?

    My batch of starline brass just came in and it's time to load up for my G20.

    Thanks!

    Lithium,

    I've got a pile of 180gr sitting on my bench and the powder trickler is currently in the hands of UPS on it's way - so hang on, buddy - got your 6! ;f

    kestrou
     
  14. Thanks, will look for your post.

    I'll start with some of the VV loads and see where I go from there on my end. ;)
     
  15. Clocked my loads today, out of a stock G20 barrel:

    6.9gr N340, Montana Gold 165 JHP 10 shot string: 1038fps, ES = 30, SD = 8.

    7.5gr N340, Montana Gold 180 FMJ 10 shot string: 1127fps, ES = 41, SD = 11.

    More do testing next week.
     
  16. Has Mcnett ever used or published data with n-105?
     
  17. Im looking for 2 basic loads for my G20. First, for 165 Gold Dots and 165 FMJ. Secondly, a hunting load for 200 XTP's. I like what Im hearing about VV powders, so any suggestions? For reference, my G20 is completely stock. I do want a full power load, but without trying to over pressure.
     
  18. I'm looking to make up a load for my Delta using VV N350 , CCI primers and 165gr Gold Dots (how is the Starline brass?) Have to admit I'm a little peeved at Lapua and Vihtavuori . No mater what powder question you have they will not give you a solid answer. I know they don't want the liability , but how hard would it be for them to actual test their powders with different weight bullets. If they did they'd sell more powder! (Sorry rant over) It should be obvious by now that VV does not list a 165 gold dot (or any other 165gr bullet) for a 10mm Auto load. If any one has worked up any #'s using N350 I'd appreciate what they found.
    PS . Is there a good inexpensive Chronograph available, (than I can publish what I find also.)
    Thanks in advance
     
  19. Not much activity in here. Got a chance to shoot some of my latest 10mm loads out of a stock G20 today and thought I'd post something:

    VV N340, loaded to 1.260 OAL, Bullets are all Montana Gold. Brass is new Starline brass. Lit with Winchester Large/Magnum Primers. Temp was around 82 deg.

    10 rounds each.

    9.0grs under 155 JHP -> 1317 fps, SD 10fps
    8.6grs under 165 JHP -> 1239 fps, SD 8 fps
    7.8grs under 180 FMJ -> 1139 fps, SD 4 fps
    7.0grs under 200 TMJ -> 1039 fps, SD 4 fps

    These loads range from 41,400 psi to just under 44,000 psi according to Quickloads's calculations with corrected case capacity using (H20). My goal was to stay under the original 10mm 44,000 psi spec pressure.

    I didn't see any signs of overpressure but will clean up the brass and re-inspect. I'm sure there's room to go up but it'd probably be easier to start with a more appropriate powder.

    Accuracy was good. Shot at 25 yards off a bench and the smallest 10 shot group was only about 3.5" with the largest group being approx 6.5".

    For reference I also shot two factory loads I found at Cabelas:

    Buffalo Bore 180gr Gold Dots -> 1284fps w/ SD of 18.
    Hornady 200gr XTP -> 1030fps w/ SD of 38.

    Have fun and please work your loads up carefully.
