Reloading the 30 luger

[Karl]

My M1900 Luger slugs at .304 lands/.312 grooves. I am currently using the Berry .312 plated 71 grain round nose bullets with 3.7 grains of Red Dot. The powder charge is tuned to the leaf recoil spring and is probably not relevant to coil spring lugers.

Karl,

Standard groove, on the 7.65 Parabellum, is in factory spec. at .311 inches.

This diameter has always shot perfectly for me in my 7.65 Lugers. In fact, lead .313s have worked perfectly for me in a pinch.

All the best,


Sieger
