9mm and bluedot

im wanting to use up a large supply of blue dot that i have, i see that lee's modern reloading lists 8.0gn as start and max both, for 115gn jacketed bullets. is this safe? i see many max loads with this powder/bullet weight maxed out around 6.5-6.9gn. plan on using win 115gn hp bulk bullet, win cases and fed sp pimers col 1.169. if anyone can reccomend a known safe blue dot load with shorter c.o.l. id appreciate it. thanks to all who reply!!!

Blue Dot will work in 9mm (I don't know about that particular load), but you can always tell the BD shooter at the range by the amount of unburned powder he's leaving behind, and by the size of the muzzle flash when he shoots.

I've tried Blue in .38/.357 and a couple of other cartridges, and it can be frightfully dirty (as can Red Dot). You can, however, make some real thumper loads with it in the larger calibers, like .41 and .44 Mags.

In the smallish 9mm case, anything much over 5 1/2grs is going to be nearing a compressed load. If you're using a progressive loader watch-out for powder spills as you index.

The Alliant manual lists 8.0 grains as a max load for the 115grain fmj (min oal of 1.120). I just don't see how you can get that much powder into casing.

Lots of luck.

Hello. This Blue Dot 9mm load has been satisfactory for me:

Based on 10 shots fired 10' from the chronograph screens, average velocity is
1166 ft/sec from a Browning Hi Power and 1168 from a CZ-75. It gets 1024 ft/sec from the Springfield XD.


Best.

I loaded some9mm w/ 7gr. BD under a 115 Berrys round nose, max. OAL, and shot them out of a G-17C. Big flame, big bark and a unburnt powder in the face and big flakes all over the place. I don't think BD is very good for small cases, for that matter I didn't care for it much in 45 acp either. I have about 4 lbs of the stuff I hope I can get a good 44mag lever gun load out of.

Like Mr. Camp, I have used Blue Dot in 9mm loads for years. It will compress easily and that is a good thing, because the closer you get to a maximum load with Blue Dot, more uniform ignition and performance can be expected. From a SIG P-226, with Winchester 115 gr. JHP's and WSP primers, Win brass, nothing has ever shot better. At 50' I have gotten many sub 1" groups. 8.0 grs. is a safe load, but you will need to load to a proper OAL. In the SIG or other long throated pistols, I loaded it to 1.142" (29mm) for shorter throated pistols like the CZ 75, I load to 1.122" (28.5mm) and this is a typical length you will find with factory JHP ammunition. For FMJ, stick with 1.142" or longer. Smoke 'em if you got 'em.

Do the shooters around you a favor...dump the bluedot and switch to a powder that doesn't rival the 1980's smog of Los Angeles. Bluedot is just plain nasty and should be banned.
