30 Luger reloading question...

[Mr. 16 gauge]

All the data I have right now for the .30 Luger uses a 93 grain FMJ bullet......however, nobody makes a 93 grain FMJ bullet anymore!:rolleyes: I see that there are some 85-86 grain bullets out there for the .30 Mauser.....could I use these in the .30 Luger? How would I go about figuring out powder charges, ect. for this safely? Thanks in advance.........

Mr. 16 gauge,

Interesting question. You came to the right place for answers. I do not load for the .30 Luger, but I would check with Lyman and Speer and Hornady for information as well as with the powder companies for guidance. Be well.

You might try it under 7.65 mm Luger ( Parabellum) or 7.65 Bergmann. The only data I have is 4.8 grs. of Unique with a 100 gr. bullet. You could start with that and work up if the gun does not function untill it does. I would recomand you Googel those different names and something should come up.

I googled up this page showing a 90 grain Hornady XTP load......

In the absence of better data for the lighter bullets, I'd try reducing the powder load by 10% (making sure my powder CAN be safely reduced!) and keep track of velocities and pressure signs as I gradually brought it up to the velocity I wanted.

Mr 16,
Take a look right here:

http://www.loaddata.com/members/search_detail.cfm?MetallicID=4497&caliber=7.65mm&caliberid=53&header=7.65mm%20Caliber%20Reloading%20Data

the difference in an 83 gr VS an 85 gr is about zip when you are pushing the bullets at a reasonable pressure.

This link seems to indicate that Winchester offers a 93 grain bullet for the .30 Luger. Hope this helps. All the best...

Ok,
I looked at my old Lyman books last night, the below info comes from Lyman #45, my other response was without my refrence library:

Bullet - Powder - Start - Max - Accuracy

85 -- B'eye -- 3.8 -- 4.2
---- Red Dot -- 4.0 -- 4.5
---- Unique -- 4.6 -- 5.2 -- 5.2

93 -- B'eye -- 3.5 -- 4.0 -- 4.0
---- Red Dot -- 3.9 -- 4.3
---- Unique -- 4.4 -- 5.0
---- Factory Duplication -- Red Dot -- 4.3

The 30 Mauser data can not be used in the 30 Luger as the 30 Mauser is a larger case (.850 VS .990) and, a load example is that the Mauser start load for an 85gr is the max load for the Luger round or 4.2 gr of B'eye with a max in the Mauser round of 5.0 which would be near 20% above the max in a Luger round.

The cast loads for the Luger were substantially the same as the jacketed loads with the accuracy loads in the 84gr and 93gr cast bullets changed to B'eye and Red Dot respectively. The gun used was a Luger in 30 Luger.

The accuracy load for the 85 was 1113 fps and the accuracy load for the 93 jacketed was 1123 fps with the factory duplication 93 gr load being 1136 fps.
