i tried to get some 231 today. all they had was blue dot. last container. so i grabbed it. in my reloading book. nothing shows for 115 grain (9mm) or 23o grain (45).

any help?
 
Alliant 2000 data has 9.8gr w/ 230gr JHP for 915fps; 8.5gr w/ 230gr FMC for 900fps

The same manual also has 8.0gr w/ 115gr FMJ for 1190fps.

These are max loads. Starting loads would be a 10% reduction.
 
I have used blue dot in 9mm and if available you will do better with a heavier projectile. 124 grain XTPs/FMJs do well for me with blue dot. I'm not going to throw out charges because I do not have my load records or other data sources near.

In a subcompact it's flashy.
 
The 9mm develops enough pressure to burn Blue Dot well though the small case capacity is limiting. BD works ok for 115 and works better as the bullet weight goes up.

I've tried BD in my .45 and it produced sooty and carbon scoured cases. The .45 ACP just doesn't produce enough pressure for it to burn well. It sends the bullet down range but makes cleaning the cases a pain.

Works great in high pressure magnums.

I agree I tried BD with 230gr jacketed buy the time you get it to burn clean you are overpressure.
 
hopefully the 200 grain will be a little cleaner
I think it works the other way round, lighter bullets faster powder heavier bullets slower powder, thats my experience. The heavier bullet provides more resistance to give the slower powder a more efficient burn.

Haven't tried it yet. I'm used to 231 with 230 grains. Never reloaded 9mm. With the market how it is. I gotta make do I guess. All I could find was blue dot. For bullets. Just 9mm and 45.
 
45 acp Blue Dot

CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK.

In the 45 acp-Blue Dot- 11.0 gr-200gr LSWC (my hard cast bullet*) -WLP maximum hot load. Ok in S&W 645. Loading data not found else where. Start low, work up. http://www.stevespages.com/page8a.htm

I am going to say I don’t recommend Blue Dot in the 45 ACP, or any pistol cartridge. I bought a keg and tested the stuff and it only really “works” in magnum applications with jacketed bullets. Using it with magnum loads with lead bullets gave horrible leading. Tried it in 9mm too.

The problem I have with Blue Dot in lower pressure cartridges are the horrible extreme spreads you get showing that it is inappropriate for the application.

I also found that Blue Dot gave a hard recoil. This is not good as a high residual breech pressure at unlock pushes the slide back hard. I had a M1911 peen out (and not with Blue Dot) and since then I have been leery of slow burning powders in these actions.

However, the data below may be a start. Compare against the SD’s and ES’s of Bullseye, which is the powder used in the 45ACP all the way back to the original 1910 test cartridges.

Kimber Custom Classic

230 gr LRN Valiant 4.5 grs Bullseye Mixed Brass WLP
OAL 1.250" taper crimp .469"
21-Jun-06 T = 97 °F

about 2" high accurate, stout recoil

Ave Vel = 805.2
Std Dev = 11.4
ES 54.08
High 836.9
Low 782.8
N = 32


230 gr LRN Valiant 7.7 grs Blue Dot Mixed Brass WLP
OAL 1.250" taper crimp .469"
21-Jun-06 T = 97 °F

about 2" high, accurate, not as accurate as Bullseye . Long ejection distance, stouter recoil


Ave Vel = 801
Std Dev = 29.12
ES 118
High 861.1
Low 749
N = 32
 
I don't know about .45 but in/for the 9, it is a slow process and if you're using a progressive, not really advisable at all. You gotta pretty much mound it up and it'll get flung off/out with the rotation of your loader.
 
I have tried a lot of different handgun calibers and loads using Blue Dot, and found it is the best choice in 2 loads only. First, 10.0gr under a 180jhp in 10mm. Full power, with lots of flash, fun to shoot, no pressure signs in my 1006. Second, 15.0gr under a 240jhp in .44 magnum. Economical way to get full-power loadings without using 8-10 additional grains of even slower-burning powder. My 77/44 rifle is real good with this one, and not much else. My Redhawk shoots it pretty well also. Caution - this load is above maximum in many loading manuals.

For just about everything else I would choose other powders.
 
Don't like Blue Dot for pistol loads especially 45ACP and it's a poor performer in 9MM. With the cost of primers and bullets I wouldn't waste them trying to get a good load with Blue Dot in 9MM or 45ACP. Too much unburnt powder will end up on the shooting bench.
