Seiger,

My normal shooting load consists of 7.5 grains of Blue Dot with either a Remington 115 grain jacketed hollow point, a Remington 124 grain JHP, or a Hornady 124 grain FMJ truncated cone. The 115 and 124 grain bullets are loaded to an overall loaded length of 1.120 to 1.130 inches (When using fmj round nose bullets, I like a overall loaded length of 1.170 inches). Velocities run around 1170 fps for the 115 grain load and 1100 fps for the 124 grain load from my Sig 226. Bullet shape effects the velocity and when using Remington 115 grain fmj round nose bullets, which have smaller bearing surface, the velocity is 1085 fps.

I also use 8.0 grains of Blue Dot with the Remington 115 grain JHP, but not in my lugers. My Browning Hi-Power GP Comp likes the 8.0 grain load better than the lighter load. This load produces around 1400 fps out of the long barrel of the GP Comp (It surprised the heck out of me the first time I chonographed it...). The Remington jacketed hollow points feed perfectly in my lugers, though who knows if they will feed in everyone else's...

Different guns seem to prefer different loads. Some of my guns shoot substantially better with one bullet weight over the other, but I've standardized on these loads because I can almost always get one of them to shoot well out of almost anything.

Please note that I use Dillion dies, which size the case quite a bit and produce a "wasp-waist" looking cartridge. I have found that when using dies that don't size the case so agressively, the powder charges must be increased slightly to get the same velocity.

Sieger already know this, but to anyone else, please pay attention to the overall loaded length. Loading to shorter length increases pressure very quickly, and it also adversely effects functioning, especially in lugers. The Hornady manual lists overall loaded lengths for the 124 grain truncated cone bullet that are ridiculously short and would most likely cause pressure problems with the loads listed above.

Seiger, if I can provide additional information, please do ask. I can try to answer when I'm at home and have my reloading records available.
