I am interested in knowing if i can use 9x18mak in my S&W 9mm
parabellum? They chamber well, tight fight, brass is a little shorter,
less lead grain. Tell me what you think!

"One other requirement the Soviets had in the development of this
ammunition was that they wanted to make sure that if they were ever
invaded by NATO, foreign armies could not use captured ammunition
supplies in their own weapons. 9x18mm ammunition uses a slightly
larger diameter bullet than other 9mm rounds. 9 mm Parabellum is 9.017
mm (0.355 inches), however 9x18mm rounds are loaded with bullets
measuring 9.220 mm (0.363 inches)."

NO!! A .361 bullet down a .355 bore is not a good idea.

The 9mm Parabellum uses a bullet .355" in diameter. The 9mm Makarov
uses a bullet .364" in diameter. Only do this with a pistol you don't
mind destroying or if your name is Clark Magnuson.

NOT interchangeable, Makarov bullet is .363-365" where 9x19 is .
354-356" nominal. Your S&W must have a fairly loose chamber, too.
Take video and post it, if you survive!

Interchangeable NAMES, same round:
9x19
9mm Luger
9mm Parabellum
9mm P
If there's anything BUT those on the ammo box, DON'T USE IT in a 9x19
pistol.

I think the bullet should swage down that much without a problem, but
I don't know. The tightness will increase pressure, but you have a
lot of headroom on the pressure...

I think the biggest problem would be poor headspacing and the
resulting misfires.

Isn't 9x19mm ammo a lot cheaper than 9x18? (I just ordered a CZ-82
pistol about 20 minutes ago. Gonna have to find a source of 9mm Mak
ammo and/or bullets, dies, trimmers, etc.)

Well, at least you asked before trying it.
Actually, not an unreasonable question given the fact that they both
have 9mm in the name.
And there are lots of cartridges called 9mm something or other.

The short answer is don't do it. There is a bullet diameter difference
that would/could cause high pressure spikes, and possible damage.
9x18 Mak is 0.364
9x19 Parabellum is 0.355

Check out what SAAMI has to say about chamberings and ammo at:
http://saami.org/specifications_and_information/publications/download/SAAMI_ITEM_211-Unsafe_Arms_and_Ammunition_Combinations.pdf

(cut and paste if necessary)

For your specific question you need only go as far as page 3.

And remember, these are not merely suggestions, but are instead warnings
of possible dire consequences should you choose to attempt any of these
"alternatives".

Stay safe,

Tom

As many other will have pointed out the bullet is too big. And just so
you know (and It may be the reason the Mak appears to chamber well) the
9mm is supposed to headspace (stop falling into the chamber) by the case
mouth, That little rim of metal that holds the bullet in. So you can't
use the 9x17mm / 380ACP / 9mm short either even though it has the right
size bullet.

THEY ARE DIFFERENT DIMENSIONS AND THE 9MM PARA HAS A TAPER THAT THE
MAKAROV LACKS.

Such an act is foolish as well as potentially dangerous.

I found the best price on 9MM Mak ammo from www.jgsales.com on both
the cheapie steel case Wolf brand and the reloadable S&B brand. I have
an advantage though of living with in a 2 hour drive of J&G so I can
beat the freight charges but have to pay local sales tax. If your a
bullet caster I've had good luck so far loading bullets cast from a
Lee mold. If you're a reloader your CZ-82 is going to make you work
scrounging brass. It ejects the brass quite violently in all
directions. If you're loading to punch paper or killing tin cans keep
your loads as mild as possible. Enough to cycle the action but not
enough oomph to eject the brass a country mile. Get a marking pen and
print a wide stripe on the head of the 9X18 brass. Makes life much
simpler separating 9X18 Mak from 9X19 Luger brass.

I am a bullet caster, but I was thinking about buying a thousand cast
bullets to get me started. The gun came Friday, and I took it to the
range briefly yesterday with some Silver Bear JHP's (the only Mak ammo
available locally.) I was expecting a sharp recoil and for the empties
to be thrown into a low orbit (my P3AT does both of those) but the
recoil wasn't bad at all and I easily found all but one piece of my
brass (I know it's not reloadable) about 10 feet away and mostly in a
pile. That's with the original stock spring.

I like it. I'm a southpaw, and all the controls are ambidexterous
except the slide lock. The trigger is very nice, even the first
double-action pull. And if you have a misfire it is restrikeable, just
pull the trigger again.

Okay no i am no expert and neither do i own any firearm. If it is a revolver it techincally
would be able to fire it.same with a semi auto but the round will not have enough energy to
load the next round in the chamber(in theory).
