All this means it is a recognized "standard" for loading ammunition for 9 MM. Energy is 466 ft/lbs with momentum at .689 lb-seconds and higher than the 147 grain JHP load. Recovered diameter is ¾” or better while the possibility of over-penetration is significantly reduced. If the folks in management read this I hope they’ll consider some of my points. And even for the newest wonder-bullet, their performance parameters are based on necessary energy levels. Rob Behr and I had a good discussion some time back about the case-head strength of the 9 x 19mm cartridge. Most manuals stop at 147 grains, though Hodgdon and Vihtavuori have data for 150 grain bullets. CIP has since lowered that to just above 34,000 PSI. Chronographing 10 rounds in a string works fine for me. The first step has to be a conscious decision concerning the possible ramifications of using your own handloads for defense. Yet, there are those like Lyman and Hodgdon that continue to test pressure in CUP to make sure their data does not exceed established limits. 2.8 gr. 9mm caliber (355, 366 dia) 380 Automatic 90 380 Automatic 95 9mm Luger 115 9mm Luger 124 9mm Luger 125 9mm Luger 147 9mm Largo 9mm-Bergmann-Bayard 115 9mm Largo 9mm-Bergmann-Bayard 124 357 SIG 125 357 SIG 147. I feel that you should find it incumbent upon yourself to verify any of the techniques I will provide. I’m trying to get close to the Hornady “American Gunner” load velocity of 1170 fps. Not on an internet gun forum, but in your handloading manuals.9mm Para+P  9mm Parabellum data. You may need to download version 2.0 now from the Chrome Web Store. The lower you can get the SD of a load the better chance you have of all 10 rounds in the string (or how ever many you fire in your strings) the more similarly those loads are likely to perform on target. In particular, some excellent research by Charles Schwartz whom I believe brings some invaluable data to the discussion with empirical evidence for those doing their own testing in regard to expansion, penetration and predicting the performance of jacketed hollowpoints in 10% ordnance gel, the perceived grail for testing defense load effectiveness these days. The momentum isn’t terrible, but with energy so low I’m just not going to count on ballistic gel performance being conclusive enough for the real world. Another way to prevent getting this page in the future is to use Privacy Pass. The more closely that each round in the magazine performs exactly the same, the more consistent you can expect the result to be at a time when you really have to put it to the test. I’m mainly concerned with increases of .001” so I use my Mitutoyo dial caliper. http://www.amazon.com/Quantitative-Ammunition-Selection-Charles-Schwartz/dp/1475929064. 9 x 19mm or .45 ACP. A blend of traditional and modern powders was used to develop the accompanying 9mm Luger load data. My background in design and related engineering disciplines was a great benefit to me, but none more so than the handloaders who preceded me whom made invaluable contributions in writing from their own experience. In the case of my .45 ACP XTP load that’s 230 x 900 / 225218 = .919 lb-seconds. spec. While I’m on this subject, let me touch on poly-coated bullets for a moment. They share a common feature with Hornady’s Interlock rifle bullets with both having an internal interlocking ring that binds the core to the jacket. I use 7.0 gr Herco under a 115 gr Gold Dot for a +P load in my CZ75. Plan to use in two accurate CZ's, a 85 and 75BD. In the response I was told that it appeared that some of my statements contradicted each other so I want to cover this in regard to the statement I made earlier about pistols with short chambers. And just as I mentioned pressure increasing with shorter OACLs, it works the same in reverse. IMO, somewhere in the middle. For those of you who have not started loading for rifles as yet, you may see slightly exaggerated statements regarding the difference between loading for handguns and loading for rifles. Before the .45 ACP Golden Saber data was developed I used the data for the 185 grain XTP: 1152 FPS with 9.9 grains of Silhouette. I have Unique, Universal Clays, BE-86, WSF in enough quantity to load all the bullets I have. If we increase velocity and energy at the muzzle we also increase impact momentum, lessening the effect of potential clogging. Submit a question to the Ballistic Experts in our Lab. At that point, rather than increase the powder charge further and for the benefit of readers who might not be able to load as long as 29.5mm/1.161”, I shortened the OACL to 29mm/1.142” to get the additional velocity. If you ask a statistician about SD, Standard Deviation, you’re going to get a rather lengthy answer covering things like confidence limits, population size, etc. I don’t have the pressure testing equipment I’d like to, but from the 35,700 CUP data I’ve been using for many years none of the loads we’ll be discussing should even reach 35,000 CUP. Momentum x (velocity / 2) = Muzzle Energy. So, let’s take a look at some essential tools you’ll need, particularly if you decide to load up toward and into 9 x 19mm +P pressure levels. Magnum. Min Charge Max Charge Optimal Charge Bullet Make Bullet Type Primer Notes; Accurate - Nitro 100 NF: 115 gr. And just a FYI, but with 9mm Major loads, you do not reload the spent brass a second time. I can’t remember what his powder charges were now but he found velocity comparable if not better than using 3N38. As we examine some historical aspects of the cartridge it would be difficult not to consider some of the debate regarding defense load effectiveness or the elusive subject of “stopping power.” In my opinion, in just the past few years we have seen some significant achievements. Possible OACL.” Regardless of which autoloading handgun cartridge you load, the bottom of the case should NOT extend beyond the barrel hood. Considering the longer OACL I find that very consistent with the Accurate data as well as the results I get. Let’s talk about Sectional Density now and hopefully they’re given in your load manual. Well, in my case I put 10 rounds over the chrono but only fire a few in the water jug test. He had a very good idea and tried using Accurate #7. Sure, you’re wallet is a deciding factor, but low cost cast lead and particularly poly-coated lead bullets will stretch your shooting budget. In the Western #5 load guide we see that the data for the powders used for 9mm loads are listed by burn rate. But, when safe pressure allows you to increase the powder charge for higher velocity, things change for the better. Craterring is definitely one condition that is an indication of overpressure and there are others like pierced primers. Only one other load did, a 9mm 147 grain JHP load rated +P+ that the DPS passed on it because of the negative connotations that might be associated with the +P+ label by an uniformed press. Flattening of the primer is not always conclusive with handgun loads as compared to higher pressure rifle loads. I have found that just about everyone’s pet theory has some merit. 1. The other part that I found rather dubious was the statement that, “our test barrels are SAAMI spec.” That’s all fine and dandy, but SAAMI allows a variation from minimum to maximum where all are technically, “in spec.” The problem with minimum dimension barrels for testing is that the rated pressures are too high for the corresponding velocity. For pistols with barrels of 4.5” or longer you may see an increase to 1150 FPS from your service pistol. Loads for 9 MM Luger: (Note: These are near maximum loads, you should use 10% less to start.) I’ll be quoting those for Hornady XTPs but there should be little or no difference regardless of bullet manufacturer. In the case of new handloaders and loading for any handgun cartridge I’ve always advised that they use a powder that will fill at least 50% of the case. Truth be told there aren’t many defensive cartridges I load where I can’t get standard deviation below 10 using True Blue, even with .357 Magnum loads for my 2 ¾” Ruger Speed-Six. To make things even simpler, you can just shorten your handloads to the next lower .5mm. Click on a term to search for related topics. 9MM Standard Pressure, as layed out by SAAMI Specifications is 35,000 PSI. One reason I’ve never updated mine. If you feel like you’d prefer the 147 grain SPEER Gold Dot, the TMJ data will work. 9mm loads? 45 Colt. I feel more comfortable when momentum is above .650 /lb-seconds. With your caliper, say you measure the “Max. Regarding my 230 grain .45 ACP load, at 863 FPS it was barely contained by the 4th one gallon water jug. If you Google overpressure ammunition you can learn a few things on the subject. Lets take a look at some popular powders in a defense load... 9 MM Major (Open Class) Here is a whole bunch of "slower burning" powders loaded to 165+ Power Factor using 124 Grain Bullets This is defined somewhat similarly to the case of adequate bullets for big game by Sectional Density which we will also cover. They had also started another practice; that of using a CIP minimum dimension barrels for testing. As an example from the Lyman graph I mentioned, there was an increase of .001” when raising pressure from 30,000 CUP to 35,000 CUP and another .001” of expansion when going from 35,000 CUP to 40,000 CUP. This is not some exercise to get to 38,500 PSI; its about getting as much velocity as possible with acceptable pressure. For clarification, the 9mm NATO often utilizes a 124-grain FMJ RN “Ball” bullet at 1,250 fps, which is loaded to higher pressures than 9mm Luger commercial ammunition and is listed with a maximum average pressure of 36,500 psi (proof loads are 45,700 psi). I recently saw the question of handgun cartridge energy come up and it was addressed succinctly by an experienced hand who simply stated ( to those who believe handgun rounds do not have enough kinetic energy to make any difference in terminal performance ) “shoot the same weight/same velocity FMJ ( or any non-expanding bullet ) and JHP into water jugs and see if you notice any difference. 9mm Luger (Parabellum) Load Data. In a SPEER manual the data should be the same for both bullets. To avoid confusion at this point we’re talking about a longer 147 grain JHP. As far as Western Powder’s are concerned, for 124 gr. Penetration completely through 4 jugs is excessive and a lack of expansion will be the culprit. I live in the real-world, the physical world with physical solutions. Charge at which time you should start measuring case-head diameter before and after firing. To maximize performance, the ballistics experts at Hodgdon Powder Co., Inc. have developed a comprehensive Reloading Guide to provide handloaders with current data for Accurate Powders. As we get into pressure lets start by clearing up another misconception. :scratch: I carry 124 gr Hornady XTP +P rounds and practice with whatever cheap stuff I have on hand.
