Hot Ammo?

Hi,

The luger was designed around the 9mm luger round, so in theory it shouldn't have trouble with 9mm luger rounds that follow the same specifications as the originals.

The +p and +p+ are mainly designed to go off at any given time, developing a velocity that maximizes impact. The performance of the round was deemed more important than the damage it did/does to the gun it is fired from. So not a good choice for a 70 - 100 year old pistol.

The luger also hates rounds with an OAL that is rather short. The maximum SAAMI length for a 9mm round is the minimum length of the old world 9mm luger round. Hollow points usually don't feed very well either.

Winchester WalMart 115grain is a good luger round. OAL is decent, shape is classic and load is up to the specs.

In the old world we tend to use Sellier & Bellot 124 grain, as it's available, relatively cheap and up to the luger's preferred OAL standards.

Modern powders seem to have a pressure curve that differs from the old smokeless powders used in the first half of the last century. This also makes it a bit more difficult to find a good alternative load.

In my opinion, hotter loads are never the solution to cycling problems. The solution is to check what part of the package is causing problems, if any, and correct it. A normal 9mm luger should function with WWW 115gr., if it doesn't, something is wrong.
