This is like a year old?
How about letting this thread die?
Iv'e been loading Blue Dot for 30 years,unless they changed it I don't see a problem.There are more good powders now,but when Blue Dot came out it was better than 2400 and H110,which both left 10 to 20 percent unburned powder.Or Unique that was dirty.Since the warning Iv'e shot .357,.41,10mm and.40's with no problem.I have noticed that some of the older Speer manuals are loaded hotter than the new ones.I use 12 grains with 125's and 10 grains with the 158's.
They changed it. That's what caused this whole problem!
I've been using Blue Dot for 158g cast bullets in 357mag.......loaded down in a "Cowboy load"......should be ok for this purpose........
.....but, I'm adding this note to my reloading data.
thanks for the "heads up".
After retrieving my load notes, I see I have a 357mag load using 125g copper plated bullets and Blue Dot powder........that load is now noted with the warning.
Just saw this. Haven't used BD much in the past, but picked up 5 lbs. last year when 2400 and W296 were hard to find.
Last fall I loaded 100 rounds .357 125 gr. JHP using magnum primers (Winchester) and 11.6 gr. of Blue Dot. Then I loaded 50 more rounds of the same combo using 12.6 gr. BD. Thought they'd be safe enough as they both were below starting load in at least one of my manuals.
None of these have been fired. What think you? Teardown???
If I shoot 'em, it'll be in either a 586 or a Blackhawk.
They'll be fine. I used to load 14.5 grains BD under a 125 grain jhp in 357 mag... that's back when Speer 11 said 16.3 (?) was the max. I never went above 15.2
I load 158gr LSWC with 9.0 grains of Blue dot. I've not had any problems at all.
I have used Blue Dot since I started loading 357 loads for silhouette shooting years ago(1987) and have recently loved using it in my 10mm. I especially love the flash of my 10mm loads when shooting indoor IDPA shoots.:embarassed:
FWIW: I have had good success with 9mm x 19mm with 115gr and 8.0 Gr Blue Dot w/ 1.120 OAL. The compressed load burns far cleaner than a stanadard load in other calibers such as 38 spcl.
Surprisingly accurate in the 9mm G17 platform.
I load for 9x25 Dillon. I run 90 grain XTP's over 17 grains of Blue Dot, i get over 2100 fps. No signs of over pressure. ( Do Not copy this load unless your experienced and know what your doing.)
Been using BD for about 30 years to drive 158 gr. bullets of various designs. For the past few years I've used 12 gr. as my exclusive rifle load.
Great performance & I see no reason to quit using it in my .357 rifle reloads.
Blue Dot is my exclusive powder of choice for 10MM, 357 SIG and .40 S&W. Best accuracy and performance is achieved with it in these calibers. I have yet to have a split .40 S&W case or guppy belly bulge with a modest yet factory like 7.1 grains over a 180 FMJ grain (flat nose). I'll keep using it for what I use it for. .40 S&W is a tricky caliber to reload. I don't have any problems with Blue Dot in it.
I've been on GT for a few years and this is the first time I looked at the reloading forum, and this thread is interesting to me. I loaded up some 110gr JHP's over BD and have had signs of excessive pressure in my GP100 - like very difficult extraction and flattened primers. They seem OK in my Contender OTT .357 Mag barrel though.
I shot max loads of BD under 158 JSP's when my GP100 was the only thing that I had to shoot silhouettes with. These seemed fine.
I'd be interested to know what your load was.
I've been using Hercules Blue Dot since about 1986 or 1988, and used the Speer 11 manual for data. Using standard primers, my usual loads were:
125 gr jhp/14.5 grains Blue Dot;
140 gr jhp/13.5 grains BD;
158 gr jhp/12.5 gr BD; and
168 gr SWC/10.0 gr BD.
The only time I noticed flattened primers and sticky case extraction was when I absent-mindedly used magnum primers instead of standard.
Have been shooting 125 gr jhp in 357 w/12.5 gr BD for years with no problem.
Love me some Blue Dot.
Me likey (love) blue dot. Never a problem w/ it. Good stuff.
BlueDot is one of my favorite powders. Gives me excellent accuracy and velocity in my 10mm/40.
