Why of course not, as that would be impossible, now wouldn't it.

Seiger,

I did post the information I found published on the velocity of various 9mm nato rounds in a thread related to this same question- either here or on the other luger forum.

I'm not guessing, data on velocity are published by the manufacturers if you just look.

And it would not be impossible to test, just tedious.

I agree that Nato ammo is not first choice ammo for lugers.

Additional info:
Seems some folks like to test velocity more than I. So in a couple minutes searching I find 6 or more "Nato" velocity tests.
You can watch the videos yourself if you wish:
https://www.bing.com/videos/search?q...ty&FORM=VRMHRS

From 5 minutes of watching several videos:
Average velocity in fps of "Nato" named ammo from:
PPU -1120 from 4" bbl, 1244 from 5.5", and 1371 from 8"
Win- 1124
Zqi- 1146

So dig in and read/watch as many as you wish.

Don,

Thanks!

In the comprehensive "Ballistics 101" data you posted last April, there were NO 9mm NATO loadings listed in it. Please confirm.

Please view the video on PPU 9mm NATO again, in FULL detail.

The PPU 124 grain 9mm NATO ammo, as shot through the Glock 19, (4.5 inch barrel, with conventional rifling) had a high of 1,261 fps with an average of 1,245 fps. The same cartridge fired from a Beretta M9 (5.1 inch barrel) had a high of 1.231 fps with an average of 1,212 fps. Please note that these ARE NOT muzzle velocities, but rather, fired at 10 to 12 feet from the barrel.

The same shooter tested Winchester 124 grain 9mm NATO (again, at 10 to 12 feet from the barrel).

S&W M&P, 4.95 inch barrel (very close to the M9 length), high 1,217 fps, 1,207 average.

These verified results would tend speak for themselves.

ADDITIONAL INFORMATION:

Here is the other PPU 9mm NATO test.

The same shooter tested PPU 115 grain 9mm NATO (again, 10 to 12 feet from the barrel).

Beretta M9, 5.1 inch barrel, high 1,260 fps, average 1,242 fps.

This load was noticeably hotter than the 124 grain PPU NATO load listed above.

The velocity differences between a 4 inch Luger barrel and the 4.5 inch Glock barrel listed above would not be significant.

Don, I don't know of any other post you may have made on 9mm NATO specs. other than the one I referenced above. Please verify and/or repost.

Thanks!

Don,

If you want to chance it, then please go right ahead.

I was involved, in a very lengthy thread, just a while ago, on this very subject.

If our readers would like to read the warning, printed on each box of Winchester 9mm NATO ammo, (the warning is readily available on the internet), they may. In it, Winchester warns that 9mm NATO ammo is loaded to pressures 10 to 15% higher than standard industry specs. for the 9mm Luger. This ammo has been available at Walmart stores from time to time, and is, apparently, a military over run with primer seals and crimped in primers.

This Winchester 9mm NATO ammo has caused breach block slap in my Lugers.

Another HOT 124 grain 9mm NATO loading, as marketed by PPU, has a VERIFIED 1,261 (maximum) fps from a 4.5 inch barrel.

Obviously, there must be a variety of modern foreign military surplus ammo available here in the U.S. This ammo was designed for modern submachine guns and more modern pistol designs than the Luger. All of this ammo should be suspect when fired through a Luger.

One final item. There seems to be quite a variety of comments on and total misconceptions (some actually comical) of the definition of, causes of, and prevention of breach block slap. Please look for a future Sticky by me on this most misunderstood topic, as breach block slap will, eventually, destroy your Luger! And no, it was non existent with original spec. German Army ammo.

Lots of info there, there are many videos so eveyrone can look at them, maybe even find "their" ammo and draw their own conclusion. The 4" bbl of the luger will yield even lower velocity than the 4.5 to 5.1" bbls noted in that video

There are at least two PPU videos, check them both out. One uses an 7.8" bbl.

If you looked at the post, you know what is in it. I did a post with nato info; please do post a link to it so we can all find it again!

As you say the info is there, one just has to look.

Isn't our main concern with shooting a Luger, is that it functions properly, and without damaging the pistol. Then wouldn't the specification we should be most concerned with is muzzle energy? If the original German Army specs are a 123 gr bullet at 1,076 fps, that's 316 ft-lbs. May we assume that's a good solid amount of energy for safe and reliable functioning, and plenty enough "for war."

Then NATO spec 9mm of 124 gr at 1261 fps would have a muzzle energy of 438 ft-lbs. If I'm doing the math right, that's a 38.6% increase in muzzle energy. That can't be good for any Luger to run a couple of boxes through once in awhile.

So here's a real life problem. When Ohio's lockdown is over for sure, I've a nephew and some grands that want to shoot my byf 42. Everyone had already bought a box of 9mm at Cabela's. I certainly don't want to damage the P.08, but shooting underpowered ammo may cause malfunctions. There's a box of Sig; 115 gr FMJ, 1185 fps, 359 ft-lbs, another kind of Sig; 115 gr FMJ, 1050 fps, 282 ft-lbs, and a box of PPU; 115 gr FMJ, 990 fps, 250 ft-lbs.

I know we can't be absolutely certain of any of these specs, made in the USA or Serbia, but they're all I have to work with here. I'm thinking the hottest is too hot. Maybe the middle one is in the Goldilocks zone? Is the PPU ammo too underpowered?

Hi Herb,

The Sig and PPU specs. you have listed look funky to me.

Do you reload at all?

If not, The Fiocchi 123 Grain Combat round (truncated cone bullet almost an exact replica of DWM's original bullet) has worked perfectly in my BYF 41 AND is NOT overpowered!

Your grand kids may have to wait a little longer until CV 19 mess straightens up.

Good shooting!

I'm not sure what you mean by funky in regards to the specs I gave for the two different Sig and one of PPU ammo.

I presume you don't mean funky, as in music, and the only other definitions I can think of are either, filthy or questionable.

The Sig specs are from right on their boxes. Like I wrote, they're all I have to work with, so I have to trust that they're reasonable guesstimates, and at least good enough for relative comparison. Certainly I should be able to trust that one box of Sig ammo is hot than the other. My question, still unanswered, is if the hotter one is too hot and the slower load not hot enough?

With the PPU ammo, the only spec given on the box is the bullet weight, 115 gr, the same as the two Sig loads. Different websites selling this ammo (when it's in stock) give different muzzle velocities. So using one of the many calculators on the Internet for calculating muzzle energy are going to give different ft-lbs depending on the muzzle velocity input. In that earlier posting I gave a low one compared to one I just now found for the exact same ammo. based on both the photo of the box and the UPC on the box.

PPU Handgun Line 9mm Luger FMJ 115gr, 1145fps, 335 ft-lbs.

Like I said, I feel I can take what printed on the Sig boxes as a good guesstimate. PPU is something else.

Herb,

I have listed the commercial ammo of my preference and knowledge of function.

Is Muzzle Energy really the determining factor, though, obviously, quite an important one?

Really, the only true test is to fire the lowest rated ammo and test it for jamming.

Use others at your own personal risk.

I may be coming off like someone who's riding the line between cautious and stupid. I'm a learner and maybe this will be a teaching moment for other shooters too.

Just to review what I've learned, that others may want to know.

124 gr, 1261 fps, 438 ft-lbs. NATO plastic pistols,not old Lugers.

123 gr, 1076 fps, 316 ft-lbs. Original German Army P.08 specs.

123 gr, 1180 fps, 383 ft-lbs. Fiocchi FMJTCEB (truncated cone) closest store bought to original specs (presently unobtainable).

Of the three types of ammo (see my earlier post) picked out for me at Cabella's while Grandma and the other girls were shopping at Ikea, I think that the Sig 115 gr, 1185 fps, 359, may be the best performer.

A decade and a half or so ago, members of this forum were very big on the 100 round Winchester White Box from Walmart. It did seem pretty good ammo for awhile. Some time ago it became inconsistent.

Thanks to all, especially Seiger.

I have long dreamed of a wildcat in 22 to 25 caliber on the 9mm or 30 Luger case. As you know the Luger is a pretty good design to start with.

Take a look at the .22 Lowenstein Luger round.
There is some evidence that Mauser considered that round in the post war Parabellum pistol.

[hayhugh]

When I first got my Lugerman .45 Luger I checked around the site about ammo. Someone mentioned that .45 steel case worked very well in this type of pistol. I took their word and purchased 500 rounds of Wolf.45 steel case ammo for use with this pistol. After reading this post I am wondering if this was a good purchase. Any comments?

Hi Hayhugh,

I know that these Lugerman recreations are quite well done, so congratulations on your purchase!

No, I don't believe that steel cased ammo should be used in any Luger. Why? Because of excessive ware caused by steel on steel contact (case to extractor, etc.). By the way, the original, late war, German steel cased stuff was marked "Not for use in Pistol 08".

A while ago we had quite a long thread discussing this very issue, so, no doubt, opinions will vary, accordingly.

Just my advice.

[Vlim]

Lacquered steel cases could get stuck in the P08's stepped chamber. Easily cured by reaming out the stepped area, but probably wasn't worth the hassle.

[Doubs]

I'm glad I reload for my Lugers. My load is listed in another thread and works quite well in all my shooter Lugers.

Steel doesn't expand or contract at the same rate as brass. If the load is hot and the case doesn't contract quickly enough, it's hard on the extractor. I don't use steel case cartridges in any of my guns from Lugers to my semi-auto rifles.

Others are welcome to use whatever they wish. Their gun, their money and their choice.
