How many use Unique powder for 357's...?
Just wondering if you use Unique powder for your 357 loadings? If so share a recipe. I have loaded some with 7.5 grains and will give them a try out today.

load UNIQUE in .357 magnum
UNIQUE was my first powder 33 years ago.
I load between 7.8 and 8.0 grains behind a 158 grain bullet. It seems to work quite well. |

How's the flash on these loads? I know it is dirty compared to most so I am ready for that with experience from my 45 ACP handloads.

The flash is not noticeable during the day. I'm not sure about twilight and darkness.
I've been using 7.5gr of Unique with a CCI magnum small pistol primer and a 158gr bullet. Works pretty well on bowling pins and steel plates. |

The new Unique isn't all that dirty. The old stuff was almost like blackpowder.
But for 357s I use 5.7 grains for 125 plated and 158 plated. I also use 5.7 grains for 230 gr RN plated 45 ACP. I also use 5.7 grains for 240 gr SWC 44 plated. (I don't like fiddling with the powder charge once it's set.) |

Pinned and Recessed, did you intentionally state 5.7 grains? Or, did you mean to put 7.5 grains?

Ranier states that when you use their plated bullets, for loading data, use lead bullet data. 5.7 grains Unique is a very pleasant load for the 357 and 45. (Sorry, I just looked at a couple boxes 44s and they're loaded with 7.0 grains Unique. My bad.) |

Sorry moderators for posting in the wrong forum; I tried out the 7.5 grain Unique loads today and while they shot very well they seemed a little lighter than I had hoped for. I will try the 7.8 max next time out to see if that is what I am looking for. The powder was not as dirty as what I had remembered with my 45 ACP loads. And I am using the newer Unique now so that makes a big difference. Guess I will pick more of this up at the next gun show.

I'll ditto that the Unique of olden days was dirty stuff. These days, it's about the same as any flake powder. I use Unique in all my handgun loads from .32 acp to .45 acp. I use it mainly because it was available at our trap club at a very good price but only in quantity and since becoming disabled I cannot shoot 25 rounds of 12 ga. in one sitting (standing?) so I use the remainder as handgun powder.

Thanks Firechicken that was what I was looking for. I had seen where some load Unique to 8 grains but still that is not going to get anywhere near max velocity or even close to factory loadings. The 7.5 load was a nice practice round and had a little more "umph" than 5 grains of 700X but still not what I was looking for. Thanks again for the powder suggestions. From what I have gathered I need to use magnum primers with these three suggested powders too?

As far as the magnum primer, standard primer thing. I try to keep it simple and use magnum primers in magnum cartridges, and standard primers in non-magnum cartridges. Probably not necessary in the Unique loads, but I wouldn't try 296 or H110 without the extra "umph" of the magnum primers and a tight crimp. Both of those powders need high pressure to burn properly.

Unique for 357 Rifle Silhouette
I use 7.5 g of Unique with a 125 g Ranier Hollowpoint with a small Federal Rifle Primer when shooting Pistol Cartridge Silhouette with a 357 Marlin Cowboy lever action rifle.
Great results at 40 to 100 meters. Rifle is not any dirtier than other rifles shooting other powders. Al |

I tried some 7.8 grain Unique loads today and they were like everyone said, medium power for a 357 magnum. Accuracy was good and it wasn't near as dirty as I thought it would be.

I started loading my .357s with 9g Unique with a 125g SJHP bullet. I tried some with 8.5 and 9.5. My Chrony says the 8.5 loads were only in the 1100s and the 9 and 9.5s in the upper 1200s. I just settled on 9g for simplicity. The Unique burns way cleaner than the factory Independence brand 158g loads I had and about the same as some Winchester 110g.
