7.65/380 interchnable?
 

Just purchased a 1923 commercial 7.65 DWM luger. Great looking gun with all matching and good rifling. Tried to insert a bottleneck 7.63 Mauser into barrel and bullet would not go in fare enough, sticking out about a good 1/8 inch. looked around on the internet and saw an article that states a.380 and 7.65 are the same...Tried to slip a 380 into the barrel and it sticks out too far also. Just what ammo am I suppose to be using in this gun?

Hayhugh, your pistol is chambered for the .30 Luger round (7.65x21mm). The .30 Mauser round is 7.63x25mm. The Germans knew the .380cal round as the 9mm Kurz (9mm Short -- 9x17mm).

The true experts will be able to tell you more about the similarities and differences between bullet weights and diameters for .30 Luger and .30 Mauser.

Just in case, never use the dimensionally similar Soviet 7.63x25Tokarev round in a 7.63mm "broomhandle". The Soviet round is loaded much hotter, and will likely damage a C-96.

yes, 7.65mm is usually called 30 Luger in the USA

32 acp, 380 acp are bullet wise, close, but not close case wise.

7.63mm for broomhandles is a totally different cartridge than 30 Luger

Ed,
I'm pretty sure that 7.65mm is the equivalent to our .32 ACP round.

IIRC, 7.65mm (the 7.65x17mm round) was the "substitute standard" round used by the German military and police during WW2.

The Walther PP, Sauer 38H, Hungary's model 37 (as used by the Luftwaffe), and the Czech Vz. 27 were all chambered in 7.65mm.

Respectfully,

yes --- but the average person will call the 30 Luger the 7.65mm Luger

So, you are correct, but calling it the technical name IMO throws people off - was not trying to correct you, I just don't know anyone that calls the 30 luger, the 7.65x21mm

Agreed. I've fired 32 ACP through my Walther PP and PPK without issues. They're both 7.65mm.

I give up

Indeed,
When I began collecting WW2 German handguns, this issue confused me somewhat. Now, when I hear "7.65mm", I think of the 7.65x17mm/.32 ACP. Yes, I've always heard ".30 Luger" or "7.65mm Parabellum". Thank you!

As always, I defer to the true experts. I've just enough knowledge to be dangerous, I suppose. I absolutely meant no disrespect!!

Haha....I think we're all really on the same sheet here. :thumbup:

Not mad, just felt that I was / Whose on first (baseball Abbot and Costello)

Thank you Gentleman, Now I don't feel so dumb, seeing that even the forum experts were in disagreement. I have ordered a box of 30 Luger ammo. Its on backorder and will not know till probably next year if it fits. Again thanks........

The only thing that downloads is a Table Of Contents...You got a direct link to the dimensions PDF??? :confused:

OK, it doesn't work for me. I get an error message when I try to click on a cartridge in the TOC. :mad:

I was hoping the entire list would download. There's not that many. Only 47 on the pistol list.
