Adding a new caliber to my reloading. I am going to try 357 SIG.
Got some Dillon carbide dies to go into my LNL AP. I have the powder (Blue Dot and Power Piston) and brass. All I need are projectiles and primers (I know, good luck with either right now). I want to get some AA #9 and will probably stick with 125 gr projectiles. Looks like Power Pistol works well too. Been reading up on this cartridge. It should be interesting. Anyone with any info/advice on a similar setup for 357 SIG? Thanks in advance. |

I just loaded up some .357 Sig this morning. 9.5 gr of Blue dot used 124gr hp bullets for .38 Super. It works good for me as I no longer shoot 38 super but had 500 bullets gathering dust. Make sure you open up the case mouth a tiny bit, otherwise you can collapse the case easy. |
| I have had success with Universal, Power Pistol, and Longshot (PP and LS for full power loads) under 115 - 124 gr. XTPs and 125 gr. TAC-XPs. I will second the recommendation for a slight flare of the mouth just keep it to the minimum that you need to cleanly seat the bullet. |

I use Tightgroup for a bunch of pistol stuff, but for 357 sig, I like Longshot. 7.8 grains is pretty good and you can go 7.2 for a lighter load.
The books say 9.3 is max. I don't think you need to go past 8.2 or so. OAL is 1.135 124 grain Montana gold or something similar. My notes on Blue Dot says 9.9 grains will give you 1293 fps and 11.0 is max at 1416. I don't have anything on Power pistol. |

Take ALL of this for what it's worth to you, for I do NOT reload .357 Sig.
I have read a lot, and I mean a LOT of questions about this round on several other forums I'm on. Many guys choose to resize/decap first in a .40 S&W die, THEN go through the .357 Sig die. Not 100% sure the reason, but it's quite popular, so there must be one. Google probably has more info, so I just thought I'd throw it out there. Also, many guys have been using 124gr 9mm projectiles from places like Montana Gold or Precision Delta. There is load data out there. Apparently they are more readily available than the 125gr 357sig projectiles. Again, take it for what it's worth, do your own homework. I don't have any information other than this, so.. |

Once you resize the body, you can lube just the neck and resize it with the .357 die |

But the OP is going to buy carbide dies, so no problems for him.Quoted: Take ALL of this for what it's worth to you, for I do NOT reload .357 Sig.

I will probably size with my SIG dies and lubed cases. I can always tumble after to clean the lube.
I am glad to hear more than a few using Blue Dot. It produced interesting fireworks in my 10mm, I am sure the 357 SIG would be similar. I like Power Pistol, it works well in other cals. I will give it a try. I also want to check out some VV 3N37, but I only see it every now and then. Guess I will have to pick some up next time. |

I will end up loading 357 SIG, 40 S&W and 45 ACP. From Alliant's site it would seem Power Pistol will work in all 3. I will keep the Blue Dot and PP but may get some Bullseye for the 45.
I think VV 3N37 will work in all 3 as well. Oh well, the fun of experimentation. Luckily my wife wont kill me for buying supplies to support my hobbies. |
