Blue Dot load for 357 and a question
Hello,
Before work became all consuming I used to load quite a bit but have gotten away from it. Now its time to get back to what is important in life. Many years ago I decided to use Blue Dot for my 357. Just would like to get a sampling of charge that others are using for 4 inch barrel 686. Now for the question, is there that much of a difference between standard and magnum primers, particularly if using a light magnum load? What would happen if standard primers were used in a 357? Thanks |

Blue Dot works best at near max loads or you will have a lot of un burned powder. Flaming Dirt;)
Follow the manufactures load advice. PS: It is not supposed to be used with a 125 gr bullet but of course there are those that have done so and that is up to them. Alliant Powder - Safety Notice

I've never used Blue Dot with a magnum primer in .357 - I use max published Blue Dot loads under my 180-grainers with standard primers and get really terrific results.

If you read the Alliant "Notice" ,please check out the temperatures that caused this problem............OK so it is not good for a cold weather hunting load. Does that mean that at "Normal" temperatures at 50 degrees or more this powder is still "Unstable" and unsafe?
Was it just one case, maybe in a J or K frame ? It would be nice if they laid ALL the CARDS on the table with this story. As for std or mag primers..............in all my bluedot loads ,you just have to see if your gun groups better with these primers at low or maximum loads,since my K and 686 will print at different points on target and also show different fps with the different loadings. My best accuracy in my 686 with bluedot with cci500 primers comes with the 110 and 125jhp at 1288 to 1430, 140xtp target at 1250fps and the 158xtp at 1270fps with a maximum load. The heavier bullets from 140grs actually shoot better in my 6" guns and I very seldom shoot the lighter bullets,now. |

Blue Dot load for 357 and a question
I remember reading warnings about Blue Dot and cold weather in the gun mags in the 80s.Since I shoot a lot in the winter I stopped using it.I still have 3/4 of a canister on the shelf.
|
Why just the 125gr bullet? The 110JHP gets 4.0 more grains of powder for the same pressures and it was not banned from Bluedot??
HOWEVER.....I have to admit these two bullet weights "Suck" as a hunting load unless you are after vermin or "Yotes". This slow power really does much better with the 140 or heavier bullets,anyway,so I can live w/o the 125gr and BD data, just to keep everyone happy. |

It doesn't. It just states that.... Quote:
......and if the manufacturer of Blue-Dot tells me it's dangerous to use, I listen. With the amount of other safe, accurate and more suitable powders out there, I see no reason not to listen. Others are free to do as they please. |

All of Alliant's .357 recipes call for standard (CCI 500) primers. And welcome back to the reloading bench!

I not trying to refute what Mr. Quisenberry says, it just seems to me that the .44 is close enough to the .41 that it would have the same problem with Blue Dot, whatever that problem may be. |
I have already linked the warning twice. Do we need to keep posting it.
All I want to know is where Nevada Ed got his info about cold weather?? Does he have some other document?? Hey, guess what? you are not supposed to use ......:rolleyes: |
Blue Dot load for 357 and a question
It's an old warning that came out in the mid to late 80s. Whether it came from the manufacturer or the gun rags of the day,who remembers?

R3;
A person from Alliant back in the 1980's said they were having problems with inconsistant pressures with the new tests of the 125gr Jhp bullets in their labs. 14.0grs was getting around 38,000 psi, where the new pressures for this load should be 35,000 psi per the legal staff, with the new style of "Light Magnum" guns now on the market,for everyones safty,which is a good thing. I have no idea if this was the time Hercules and Alliant powders were changed over..... or if the powders were changed at this time for the "New Cleaner" powder type improvements,just that the powder has changed and modern data should be used . As for the temperature thing.......its water under the bridge,now. Stay safe |
I can tell you first hand that Blue Dot acts crazy at 30*F or less. I built some full power loads in the summer and when I went to run some over the chronograph in December, and, yes, it was under 30*F here in Indiana then, and I was getting over 2100fps from my Marlin 1894.
Suffice it to say, that was the last I used the powder here in the great white north! :D |
I hate the stuff, but ya no what?;) I just bought a pound from my LGS as he has almost nothing left to sell.
It and a bottle of red and green dot are still there from who know when (years) I have never used the other DOTS, but Blue is OK for full mags. I was using all my H110 for the 30 carbine so I thought I'd at least get the Blue. |
Where you live, there will never be a problem UNLESS when you get frost on you oranges you decide to go shooting...... :)

If you go out to shoot and don't need a pair of long johns and ear muffs, you are good to go .........
I have a "Few" Bluedot loads in 38 spl but I have to admit that Bullseye with target loads and Reddot with High velosity loads are a lot better. Unique works with the longer barrels. Blue is just so much better in the 357 mag cases,since it is so slow..............It is acually better than SR4756 in my test since it does not spike as bad and accepts different primers better. I have yet to get a 300+/- ES with Blue as with 4756. One of these days I an going to have to buy some 2400 and find out what the best powder is...................since IMR 4227 sucks. |

Blue Dot load for 357 and a question
That's why I've had most of a can sitting on a shelf for 25 years.Why bother with a powder that's quirky?
|
R3;
I was just hoping that IMR4227 would have a little more velosity for the amount of powder that is dumped into the 38spl case. All 38 loads were tested in my L frame 357 magnum for safty and the at near or compressed loads were just under or at the start of a +P velosity. You can use 50% less powder for the same velosity if you switch to w231 powder and also have less powder flakes dropping out of the brass and revolver when the cylinder is opened. I actually had to stop testing one day when a "Standard load" from the IMR data, actually froze up the cylinder in my snub nose form the powder flakes getting into the cracks of the revolver. Removing the yolk screw was the only way to get the revolver to work again. It just needs lots of pressure to burn clean and this is not going to happen in the 38 spl loads in the manuals. Looks like the lawn is going to get nice and green this coming spring............................ later. |
I was referring to your 357 mag data in the other post. The Hodgdon/IMR online data is much higher?
I use HP 38/W 231 for just about everything. 2400 for Full Mag loads. "357 mag cases Hornady 125gr xtp oal 1.59 18.5c 1325fps 34500cup c/o Dupont data 18.5c 1230fps ............... Speer 158 Jhp oal 1.58 15.3c 1075fps 36,000cup c/o Dupont data 15.3c 1082fps cci550 mag primer.................FINALLY,but still a target load with the new approved pressers of today.? |
IMR data was with Reminton 5 1/2 primers and a 6 inch barrel.
With the difference in fps I would think this test barrel might have been a "Solid" and not vented,as was the custom back in those days and maybe one heck of a crimp,also !! We all know that a company might "Fudge" a few 100fps or so for sales but going from a magnum load down to a "Lite" mag or heavy target load , with my 6 inch 686 "Vented" barrel was some what of a surprise. Its all good ...testing out different powder is fun and I enjoy doing so,just that I hate it when you step into an elevator and say "UP" and it goes....."Down". |
