9x19 (lugar) vs. 9x18 (makarov)

[Keeperfaith]

Quick question.

can you use or do you use the same 9mm bullet (projectile) for both 9mm and 9x18 makarov round?

in my reloading manual i see a 90 and 95 grain bullet in both 9mm and 9x18 data.

At the gun show I asked a seller of components if I could use the 95 grain bullet he was selling for both 9mm Lugar and 9x18 makarov and he said
NO with great conviction.

What am I missing here?

Thanks

The 9MM Luger (9x19) has a different bullet diameter than 9MM Makarov. The 9MM Makarov bullet is slightly wider in diameter at .365 inches compared to the 9MM Lugers .355".

You can use the same brass though.

Here is a drawing that illustrates (in metric dimensions ) the differences in the rounds: http://makarov.com/graphics/9mmcases.jpg

Neither the case nor the bullet are the same.

Hi All,

I'm no expert here but I want to point out that the naming of cartridges doesn't have many rules. Even though 9 X 19 vs. 9 X 18 or 9mm Luger vs. 9mm Makarov sound like they should use the same bullet they don't. The people who name a cartridge don't have to "tell the truth".

For example the 221 Fireball, 222 Remington, 222 Remington Magnum, 223 Remington, 224 Weatherby Magnum, 225 Winchester, and several other cartridges all can use the same bullets. The 38 special doesn't shoot bullets with a diameter of .38 inches. The 44 series of revolvers (Russian, Special, and Magnum) all can shoot the same bullets, which again are not .44 inches across.

Use the name as a general guideline and then check the spec sheets to find the acutal dimensions. And as a side note - get used to synonyms; 9 X 19, 9mm Luger, 9mm Parabellum, and since it is the most common cartrdige, plain old 9mm all mean the same thing.

I hope this helps some reader.

You can't use 9x18 brass in a 9x19, but you can trim 9x19 brass to use in 9x18's, but it will be thinner than 9x18 brass after the first firing in the 9x18 chamber and it won't last as long.

Dangerous advice there.

Not really. I've used 9mm Para brass for Mak pistols for quite a while but quit because I kept getting the two mixed up and it was a real PITA telling the cases apart with just a silly millimeter difference in length.

I've used the same brass for ages, shortened tho of course.
