Home Forums Reloading Handgun Reloading Green Dot powder

I picked up a 15 lb keg of Green Dot. I have one manual with data for .38 spcl , and 357 mag. Does anyone have data for a mid-range .41 mag ? I have a lot of 215 gr swc

Without looking at my burn rate sheet, isn't it close to Unique ??

Thanks for the print out mag410.
Between Bullseye and unique I believe

Green Dot is a little slower than Red Dot, and a little faster than Bullseye.

Fast to slow:
Red Dot, Green Dot, Bullseye, Unique.

I used some Green Dot for some 9mm target loads some years back. If I recall correctly, 4.0gr under a 115gr FMJ. Seemed to work well in the Glock 17.

Fixed it for you.

I guess it depends where you look for the info.

QuickLOAD suggests the order I listed above.

I took a look at data published by Alliant, (page 11 on the link), and it has them listed from fastest to slower as: Bullseye, Red Dot, Green Dot, Unique.

Burning rate is not an absolute.

When used to load 12 gauge shot shells, the order from quicker burning to slower burning is; Bulleseye, Red Dot, Green Dot, Unique.

In the handgun data I posted above, you can see that in some calibers Red Dot makes more pressure than Bullseye with the same amount, and in some cases less, powder.

This was my understanding of burning rates.

Green Dot is an under-appreciated, and overlooked powder for pistol reloading.

Well if the OP’s Green Dot was made within the last 5 years, none of that data is valid as they reformulated both in 17 or 18 IIRC on the dates. I use the same chart for Red Dot but I picked up 16 pounds back in 05-06.
So if it’s old style he should be safe, new style I wouldn’t bet my life on it as Alliant dropped a lot of pistol data do too more recent pressure data.

Hercules quit putting powder in 15 lb kegs in the late 1970's. The page I posted is from a 1983 Hercules edition. Alliant listed virtually the same data, just with PSI instead of CUP, until they started pushing their new wonder powders.

I use Green dot in 12 gauge, 9 mm, 40 sw, 45 acp, 38spcl, 357 mag, and it works very well

GD was the first powder I purchased to load .38/.357, .44, and .45ACP. That was 1970, and I bought a 16# keg. IIRC it was around $30-$35.......for 16#.

GD burn rate is very close to 231. That's why it works well in so many pistol cartridges.

How does data for 210-grain bullets in a .41 chambering contribute to this thread?

It does have a load with Green Dot, if you bother to look down..
8.6-8.7.
Not saying I would use it, but its there....
Green dot is a versatile powder..

Split the load between 210 and 220 or 8.5 max, but be careful.



I wouldn’t do that. I use that chart for Red Dot in 41 mag. 8 grains with a 215 HCSWC gives ~1200 fps, and it’s a handful. As stated before Alliant dropped a lot of those loads, especially in the 41 mag due to updated pressure testing. Even put out a warning not to use Blue Dot in the 41.
I would start 7.5 and work up.
