I'll be ordering some Federal American Eagle 9mm FMJ from Ammoman in the next month or so. I noticed that both of these are $79 for 500 rounds, but the 115 grain are $139 per case while the 124 grain are $155.
What are the differences between 115 and 124 grain FMJ? Is one more inherently reliable (or unreliable)? Is the NATO 9mm 115 or 124? What about recoil? I'm presuming an equal load will give more recoil for the heavier round, but I don't know if they're loaded the same.

This will be plinking ammo in 2 Beretta 92's, a SIG P226 and S&W 3913. They'll also be used for a shooting class my family and friends are attending. Should I just save the $15 and get the 115 grain, or is there a good reason I should get the 124? $15 isn't that big of a deal, but it'll let me get that much more .45ACP for my 1911!

TIA

Hello. There is probably no "one or the other right answer" to your question as each gun might have a different preference. For ammunition that will serve as practice ammo that's reasonably accurate, go with the 115 gr ball. I have noted that most of the S&W mini-autos I've shot in 9mm tend to hit poa with the 124 gr. I've used both and have been satisfied with both for what it was, but realizing that it was not the MOST accurate ammo for my particular guns.

Best and good shooting.

PS: Besides, there's something nice about having much forty-five ammo.

Save the money, unless you find the 115 does not work for you. You might spend more for the 124 and find you like it less.

NATO stds have some wiggle room. I've seen NATO spec ammo from 112-124 gr in 9mm (have seen 147 and 158 gr ammo, but don't remember if it had the cross-in-a-circle NATO headstamp). Some was very hot, and some was not. Depending on components used, intended use, some lower pressure stuff is actually faster than higher pressure stuff from time to time. There is NATO spec 124 ammo loaded to over 40,000 psi that only does 1125 fps, and some 115 loaded to 36,250 that does 1265 fps for example.

NATO specs have as much to do with quality control issues as weight/pressure/velocity specs. It might not always be hot, but it should always be good. Also, some say made to NATO specs; that does not mean it actually meets NATO specs (buyer beware).

Whatever your carry load weight is, buy the same weight in practice loads.
If you carry 124gr JHP's, buy the 124gr FMJ stuff, etc.

NATO specs require a FMJ not copper clad jacketing, the primer and casing must be sealed.

The only weight that is specified for NATO use is the 124gr loading using the above bullet at a minimum velocity of 1,150fps with a maximum pressure of 40,000 cup.

Most foreign makers utilize only one run of brass and have formed the rather disturbing pattern of using NATO headstamped ammo in all of thier 9mm loadings regardless of weight and pressure/velocities.

I would reccomend that you use only commercially manufactured US maker 9mm ammo.

That said 115gr ammo for practice should be fine, using true NATO spec 9mm ammo will accelerate the wear on your pistol. Standard pressure 124gr ammo is also fine.

For my money I would save a few dollars and use the 115gr ammo.

Like I said, some wiggle room:

NATO standard specification calls for a .45gram (114.971 grains basically
115 grain) full-jacketed bullet loaded to deliver a velocity of 396 m/s (1299.21 fps) with a mean pressure to be 2050 kg/sq cm (29157.9 PSI) w/an accuracy of Merit of 76mm at 50m.

USA USA M882 NATO spec. is 8.03gram
bullet, 375m/s plus or minus 15 m/s. This works out to 123.922 grain (124)bullet at a velocity of 1230.31 fps plus or minus 49.2126 fps.

Or US Cartridge, 9mm, Ball, NATO, M882 has a max of 36,250, about 1260 fps w 112 gr bullet. There was/is a Cartridge, 9mm, Ball, for use in smgs that is not authorized for pistols that has a max of 43,000, about 1125 fps w 124 gr bullet. I've been issued M882 ammo w 115 gr bullets. Go figure?

The Cartridge, 9mm High Pressure Test, M905 has a max of 50,000.

From TM 43-0001-27 (April 94) May be a newer one? I've been retired a few yrs. :wink:

There is ammo from some other countries that are "hotter" than the NATO or USA load like
Israel Carbine Ball +P 7.45gram at 420 m/s (115gr at 1,378 fps) or South
African ball 7.6 gram at 401 m/s (117.3 grain at 1,316 fps). British ball is very hot at tmes.

Another thing to be careful of is sometimes the specs are given for the ammo from shorter pistol barrels and sometimes from longer smg barrels.

Mike, do you or any of our readers have info on the Hirtenberger 9mm NATO rounds?

I have info on the subgun loads but would like to put together some data on the NATO rounds.
