| Can anyone give me suggestions for loading the caliber? I have loaded many pistol rounds but never a bottle necked pistol cartridge. Any tips or things that would help is appreciated. |

First thing is to go SLOW when setting up the neck bell. Too much and you collapse the case while flaring, not enough and the bullet will collapse the case when seating. If everything goes right you will still get a few minor case shoulder problems. It is really one of the most difficult rounds to set up for and I reload .30 Luger and 8mm Nambu as well! |

Some say not to flare the case mouth. I heard that they chamfer the inside of the case mouth so the bullet will seat this way. They said that this keeps neck tension at its greatest. Also do you use a .40 carbide die and then the 357 sig die to resize or just go with the sig dies and lube the cases like rifle rounds? |

I use the carbide .40 S&W die first. That deprimes the cases and resizes the larger diameter part of the case.
Then I run the cases through the .357 SIG resizing die - with no depriming unit installed in it. That takes care of the neck. I don't lube the case, or the mouth/neck for the pass through the .357 SIG die because there seems to be so little contact that the cases run through all right with out lube. I do slightly bell the case mouth. I've used mostly AA#5 and some 800X (nasty powder that won't measure through my RCBS powder measure worth a hoot). I've only used 124 grain hollow points so far. Hornady, Sierra, Berrys and Ranier. No issues except for the M&P tumbling some of the bullets. The Glock M31 shoots them just fine, no idea why the M&P FS does so badly with them. I just ordered some once fired brass to get started with. |

This guy was using ranier bullets and he was having keyhole problems. Plated bullets and lots of velocity was not good. He reduced his powder and had much better results. |
