I Give Up on the P08

Then I switched all my loads to 115 FMJ (back when you could still find them...) and all has been well since.
It seems to have been an issue of pressure and sufficient recoil that made the difference, however the same load/powder was used in both instances.
So to make a long story shorter, it was the ammo for me that made the difference. The right ammo and even my 4" Lugers have become quite reliable.
And I am now forced to go back to cast bullets, so the circle of frustration begins once again.

Dave:

You should try some lead cast bullets, out of the RCBS 121 grain Truncated Cone mold, with an O.A.L. of 1.142 inches (29 mms) and sized to .356 inches. For me, the best powder to date has been Accurate #5 (very accurate).

Lugers are "timed" for bullets between 115 grains and 130 grains. Other weights may or may not function trustworthly.
