I load them as they are. I've never had any problems. Nearly every .30 Luger I've slugged have been right at .310 give or take. The Hornady XTPs mic at a hair over .310 , not .312 as marked. They have been extremely accurate, and the top of the cannelure groove is exactly right for OAL on a .30 Luger.

The only "issue" has been that I had a stainless Mec-Gar mag they would bind in, due to the edge on the hollow point. I took it apart and polished the inside front with a dowel and 400 grit paper. It works fine now.

Thank you for the info. I have an old issue of The Handloader Magazine where they did an article on reloading the 30 Luger round. They used some 32Cal bullets(.312), but sized them to .309in. before loading them. It is always of interest to me to find any bullet that can be used correctly in loading the 30 Luger brass.

Hi:

Groove diameter on the 7.65 Parabellum is right at .311.

I've fired gazillions of lead .312s through my 1920 with no problems of any type.

The original FMJ DWM bullets, were, indeed, right at .309.
