    Hi guys; 1st off thanks to GSSF for putting on a great match; Anderson was a lot of fun & I like the new scoresheets. Good to meet the guys from Team Carver & Team Ameriglow.

    2nd, as usual, some of the reloaded ammo we used attracted attention for how little noise it makes. After a comment, I mentioned to the RO's that the load is actually a +p+ load. They scoffed at that & simply did not believe that such a load could be high pressure. Unfortunately, one competitor even exclaimed "cough, cough, bull****!" Well, here is the load & the predicted pressure developed:

    http://www.glocktalk.com/showthread.php?s=&threadid=315617&highlight=Quickload

    As you can see, it is way beyond +P pressures (the designation for +p+). It is not actually a GSSF load, but rather designed to meet the USPSA & IDPA power floor of 125,000 or a 147 grn bullet at more than 850 FPS. It clocks at around 876 to 900 FPS depending on the ambient temperature.

    I missed that conversation at the match.

    GSSF doesn't have a minimum power factor, if somebody thinks your loads are to light and wants to "cough" about it, tell em to go read the rules!

    I have shot stuff down at about 110 PF. If they want to talk smack who cares.

    Mike asked: "Do you need to switch out springs for that load???"

    Thanks for the Q. Joe & there is no need to switch out the Glock stock recoil springs in either a 17 or a 34 with the 3.2 load; I have not tested the load in any other 9mm Glocks such as the 19 so I cannot say for certain.

    That load runs a bone stock G17 perfectly for USPSA or IDPA. If you shoot a 34, you can likely even switch to 3.1 or even 3.0 grns & still make powerfactor with perfect function. If you shoot the 3.2grn load in a 34, then velocity will probably go over 900 FPS which is comparable to Factory-loaded 147 9mm.

    Dale & Matt - thanks for the support & see you in Richmond.

    Hey Carlitos, Ken Steakley and I were the ROs giving you grief at the plates for shooting the .22 rimfire conversion!;f I better not find any .22 brass in the bucket I collected from the range!

    Indeed the report was minimal but what caught my attention was the absolute lack of muzzle flip.

    I can't remember who had the cough but you did indeed draw some attention; I am sure it was all in fun.

    MLeeber & Ken: good thing you specified that you were running the plates otherwise I could not place you since I think every RO in GSSF has given us grief about the load; its all good. We heard it all - "will that load make it through the card-board? har har har!" or "hearing protection? We don't need no stinkin hearing protection! har har har" etc. By now we are used to it & like I said its all good.

    Thanks to you & all the other ROs volunteering - we could not shoot without you guys. I feel bad for the guy ROing 5 to glock; he was not expecting the report from my OTHER glock - the open one with compensator. I understand that poor fellow jumped a good foot off the ground the 1st time the gun went off. That gun kinda makes up for the soft shooting 17.

    i hesitate to even discuss my shooting at the anderson match, but i'll chime in anyway (hopefully noone will notice my scores).

    my load will run a stock G17 with no problems. but it will not run a stock G34. for the G34 (in uspsa), i use a 13 lb spring with 2 coils clipped off. it is indeed a light, quiet load, with little muzzle flip. unfortunately, it didnt help my shooting on saturday!

    i didnt mind the ribbing...i know everyone was just kidding around.

    mark: make sure you inspect my brass carefully before reusing it!;f

    Do you mean serious grief or just the usual teasing that we participate in at matches? I've had questions about my light loads but a quick "there's no power factor in GSSF" and "it pays the same with light loads" usually ends the conversation. Of course I'm about 6'4" so that may tend to limit the comments as well. I can't say anybody has ever really tried to bust my chops about it.

    I sometimes get tired of the "real competition" comments. Then again talking doesn't win guns or money, in GSSF or "real competition". ;)


    edit: spell check and I still can't get it right.

    it was just good-natured ribbing/joking.

    the joking stopped when carlitos pulled out the comped G34. it more than made up for our powder puff loads.;f

    There is never serious grief at a GSSF match unless you are first on the sign in sheet at the plates and it is a 2 hour wait to shoot!!!;a

    I guess I left before you shot at the 5 to G. I didn't hear anything special enough to attract my attention. I was more worried about the C-more that I'm still trying to get used to. :)

    For those interested, the Stock class load seems to produce greater accuracy when loaded with Zero brand 147 grn Jacketed Hollow Point bullets. Regards,

    What is the advantage of the load? Accuracy? Recoil? etc.

    I assume the lower noise output is a result of being subsonic? Or is there more to it than that?

    very little recoil or muzzle flip.

    The low noise has more to do with the extreme burning speed of the powder used (N310). The powder is a small grained, single base powder that quickly developes peak pressure (around 40,000 PSI; the industry max for 9mm is 35,000PSI and for +p, it is 38,500 PSI).

    After peak pressure has been attained in the first inch or so of bullet travel, pressure starts to drop. By the time the bullet leaves the barrel, there is less pressure & unburned powder vented to the atmosphere than with slower powders.

    Velocity for our load is generally between 872 to 900 FPS. We try to exceed 850 FPS; the power floor for USPSA and IDPA. A commercial, defensive 147 load usually travels at 950 to 990 FPS.

    With the higher pressure in the "first inch" wouldn't that greatly increase barrel throat erosion?

    Generally, most loads achieve peak pressure within the 1st inch or two.

    As for throat errosion, the Vihta Vouri powders are all single based powders that generally burn at LOWER temperatures than domenstic double based powders like Titgroup (which has a high Nitro content & burns hot). Throat erosion should be less with a cooler-burning powders like VV. Regards,

    147 gr. bullets have never been worth much in Self-Defense ammo, regardless what speed they run at....

    Sounds like a great discussion for the Caliber Corner. I've never had a D-1 or popper fail to be stopped by a 147 round, regardless of speed it runs at.
