Add yet the question still remains when you asked what is soo special about 1200fps, what indeed are you going to use to simulate the recoil moment of full powered or plus P defensive ammo? Although this is another topic we might expound upon. 

My two typing fingers hurt now. Good night! O0
Not HP-38. ;D

Factory SD ammo is running in the 1150 fps range, with some of the +P offerings slightly above 1200 in 124gr offerings. 1150 is easy...1200 is doable, but unnecessary IMO.

Try something like N 340, Unique, Blue Dot, or SR4756. Many of the Vectan powders will give higher velocities in 9mm. The data is out there.

Why is it that I am always the bad guy for asking questions?

I don't like the term bad guy and don't think that, so I'll characterize it as running into trouble or getting push-back.  You DON'T always run into trouble for asking questions.  You run into trouble sometimes for scattering questions in such an unfocused, tangential fashion that it's hard to keep track of what you're actually looking for, and you get into trouble for asking questions that you've seemingly already determined the answers to, then arguing with the responses or being otherwise uncooperative with the guidance you're getting from people who are trying to help you in good faith. 

And then there's the last page of this thread, which is something a little different, and it reveals itself here:


I now have three military grade poly pistols that were built around the Nato ammo. They are all heavily sprung from the factory.

Two of these guns are CZ. A P-09 and a P-07, they are rated at 20lbs factory. Same spring in both, with the shorter gun preloaded even more than the other.

Proper spring options are few, with CGW offering a 18 lb and a 15 lb. I run one of each, and although the guns will function with low powered ammo, say 115 at 1050fps or about 120PF, function is marginal and they will dump brass on your feet. 125PF seems to work well enough for ringing steel, although ejection pattern is about two feet.

The Canik is also heavy, but I have no measure. It is a Walther knockoff. I have found no(zero) spring options here. It will choke on 120PF, with 125PF working, but ? and 130PF rocking it pretty well.

^^^^^^^THESE TWO THINGS IN BLUE^^^^^^

THIS is the problem.  The last page of this thread has been in response to your floating the unwise idea of pushing a 124gr JHP to 1200 feet/sec with HP-38, well outside any published load data.  You know enough to identify this as unwise yourself.   BUT when asked why you would want to, you went down that well-beaten path of how your guns need "full-powered" ammo because they came factory-sprung so heavily that anything other doesn't run them properly.  Then you reveal these two tidbits of information below, represented in your quote from above in blue.

  • You ultimately DID take the advice to re-spring your CZ poly pistols, and they do NOT need "full-powered" ammo to function properly. They are no longer heavily sprung from the factory.  They actually function even at sub-minor power factors, but don't throw brass the way they should at sub-minor, and at the minor PF floor of 125, they throw cases a couple of feet, so presumably at a reasonable minor PF of 130, they're throwing brass satisfactorily.  AND...

  • Your Canik, which was sprung the heaviest of the three to begin with, and which you did NOT re-spring, which is STILL factory sprung, is rocking 130PF ammo pretty well.

Basically, we devoted a page of this thread to discussing your desire for a 124gr bullet doing 1200 feet/sec in terms of your needing "full-powered" ammo for reliable function.  But you don't.  The truth is that these pistols in question function fine with 130 PF 9mm minor loads.  Full-powered?  130PF is lighter than what I shoot Steel Challenge with.  You've been conducting an academic exercise on why someone might want a 124gr bullet doing 1200 feet/sec under the guise of your needing it.  And THAT makes the last page of this thread more or less pointless.  You have a forum mod advising you on how to get your pistol re-sprung to address a problem you don't actually have.  And you wonder why you get in trouble for asking questions. ;)

ID, I do appreciate your opinions and responses, yet I do believe a bit of banter on these forums is not a bad thing, such as my hypothetical question about pushing the powder to 1200, not that I was planning on it. Perhaps someone has? I do not know.

Of the three guns mentioned, there are a lot of other things that I did not get into as well, but two of them serve defensive roles and I do not plan on altering them greatly just to shoot low powered ammo. Although they work at 130PF, they do not really start working well until you are in the 140 ish range. Not sure I would trust them on a weak hand limp wrist shot with the lower powered stuff.

And again for the sake of banter, I do not believe that Wolff do any flat wound springs. I know David told me that he had a difficult time trying to find anyone to do them in the US. But that is another topic. :)

Then it should be labeled in bold at the start of the thread...
THEORETICAL LOAD DISCUSSION - NOT FOR USE

This because there are too many idiots that will scan a thread and go try some of the loads. When YOU write it, YOU have a responsibility to all the readers, present and future.

And again for the sake of banter, I do not believe that Wolff do any flat wound springs. I know David told me that he had a difficult time trying to find anyone to do them in the US. But that is another topic. :)

You said you couldn't find springs for the Canik. Period. Now that you found them, you throw in a new requirement. So tell me... If you NEED a (say for instance) 14.5 lb spring, and Wolff sends you a 14.5 lb spring what the heck does the form factor have to do with it ?

This, just for the sake of "banter".

Between the points made above and the sarcasm, I can't believe you get any respondents.

Wobbly, don't be soo mean! I can't help it if I am not good at typing! If we were just talking it would be different.

Add, what gets me is that out of all that have used this 231/ HP38 in the past, nobody ever really said if they had pushed it, or even said YEP,back off now, as you are at the top.

I am actually trying to be a bit cautious after the experience with the CFE powder running soo much faster than ID's data that I have revised my entire system in an effort to find out why! But the feedback on this powder  and load was good.

As far as springs for the Canik go, I figure if Wolff do not even offer for the Walther P99, then I do not want to be the test pilot! I will use ammo that works in the gun.

Now, as far as ID goes, I love his prolific writing, but I admit that I am a bit offended by this "You run into trouble sometimes for scattering questions in such an unfocused, tangential fashion "!

Well, it makes perfect sense to me, and I will have you know that although I do shop at Target, I am not Transgenital! I go to the mens room.

Two fingers tired again,

Hogdon data seems to put a limit on pressure and resulting speeds:  * The Hornady 125 HAP is .572" long.   compare to the PD length of .583" and seating depths.  The PD will gen more pressure at the same seating depth.

Your numbers are fairly close to what I get. I don't use that bullet but use Xtreme 1245 RN.

I load out to 1.135 and it works in every CZ I own or have owned but that doesn't mean it will work in yours.

I pay very little attention to what the books say other than minimum and maximum loads.I rarely get close to what they say the load will produce.

Like you, I'm a fan of X-Treme's bullets. I'm using their 124 RN HPCB and have been loading it to Speer's RN TMJ specs, since the X-Treme bullet's profile appears to be the same, concave base and all - close enough anyway, that it's not been an issue for me. I drop 4.4gr TiteGroup behind the 124's and I, like you, load out to 1.135" COAL on every round I load. I crimp mixed headstamp brass to 0.376" and have had no failures to chamber. I also have a good supply of VV 3N37 and have found 6.2gr 3N37 to get me the feel and accuracy I want, using that powder and also loading to a 1.135" COAL. The VihtaVuori 3N37 is twice expensive per pound and it takes half again as much, per load, as the Hodgdon, so I keep it in reserve. I've run thousands of both of these loads through my CZ's and not one of the 6 models has had a problem with them. I've seen or felt no signs of over-pressure, even though I'm at the top of Speer's load data for their TMJ bullet, using TiteGroup.

I don't chrono my pistol reloads. The only time I'm concerned with velocities is in my long range, precision rifle rounds, so I use my MagnetoSpeed to help me find my precision loads for my .308. I don't compete (cause I'm not good enough and hate not winning) and run only about 500 rounds a week through my pistols - all indoor range target shooting, mostly shooting 10 rd groups at 12 of those 1" orange stickons (4 rows of 3), stuck onto the back of a range silhouette target. My reloads right now are for trigger time and practice only. As soon as I can find some 124 Gold Dots, or another similarly performing 124gr HP round, I'll begin reloading my SD ammo.

I realize none of this has anything to do with the OP's powder or bullet combo. I apologize for that. Just thought I'd throw some more intel out there. I might not have much to say but I sure say it a lot.  ::)

Copemech -
Congratulations. Taken as a whole, this might be your best, least nebulous post ever. The thoughts are clearly expressed in a straightforward and sensible manner. The short sentences and paragraphs help project your thoughts to the mind of the reader in a logical manner. Very good!

So, it's not your typing or grammar that's being called into question. Nor is your reloading ability. It's your lack of effort in composition. Your two fingers don't need to get tired. You have good thoughts and ideas, you simply need to spend an hour cutting and pasting the ideas into a logical sequence so that others can understand.

If we were just talking it would be different.
And that is the root of the problem. We are NOT talking; we are writing. And unlike talking, when you write you can take your time with the words. Rearrange sentences to add logical flow. Delete unnecessary comments. Clarify unclear pronouns.

Quote
Wobbly, don't be soo mean!
I'm not "mean" at all. And this is an excellent example of your unclear writing. Friend, if I were truly "mean" I'd simply delete your posts and not have to spend 75 minutes trying to explain to you that it's very, very difficult to understand your thoughts.

This last post proves you can write better when you try. Please try more.

 ;)


PS. You did not take my admonition to add the red warning to the first post seriously enough to follow through, so I've done it for you.

Clarify unclear pronouns.


An example:

"He shot my chrono."  vs.  "Painter shot my chrono."

This is clear and meanO0

If you compare closely HDY HAP and PD JHP, you will find that HAP have straight flat bottom and PD JHP have recessed, concave buttoms. Therefore while loaded to the same OAL they have the same pressure even if bullet lenght is slightly different. I have confirmed it by testing and load them for BE matches interchangeably without any dies adjustment. The same velocity and point of impact. HDY HAP have slight edge in the accuracy at 50yards and PD JHP is much cheaper and good for 25yard line.

Thanks Boris,  PD is recessed 0.145", so you're right on.
