How's Blue Dot in 9mm?

Have never loaded 9mm with it. Is it dirty, inaccurate or big with muzzle flash? Does anyone have a 9mm Blue Dot load they like? I load mostly 115 gr bullets; some 125 gr.

Got 5lbs. that was intended for the magnum revolvers, but now that W296 is available again, I'm looking for another use for the Blue Dot. Is it OK with magnum primers at starting load levels?...I've got a bunch of them too.

P.S. I read the Blue Dot caution sticky

Blue dot is really slow and has wicked pressure spikes.

I still have a few pounds of it that I bet I never use.

BlueDot runs best at the top end, downloading only makes it dirty & muzzle blast/lfash greater. It's not the best choice for 9mm except in +P loads IMO, & w/ hevier bullets than 115gr. The mag primers are what may lead yo uto pressure spikes w/ BD. Use std primers. The Speer manual has good BD loads for 9mm. BD is a good choice in the 357sig, 40 or 10mm though. Pressure run high enough to give good combustion. It still has a large flash & blast though.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".

I run my Montana Gold 115 grn. JHP at +p levels, very accurate! In my C models a little dirty, but no big deal (not worth changing).

I like it for max power 9mm +P or +P+ loads with 147gr bullets.

I used to load 115 grain Sierra jhp's over 8.9 grains BD; compressed load. Pretty clean at that pressure level and definitely a max load. It gave 1275 fps from a G19 IIRC.

Have since switched to 124/125 grain bullets and haven't used BD for those loads. I've been using BD mmore in 357 mag, 44 mag and heavy 45 Colt lately.

Oh, and definitely use ONLY standard primers at higher pressures when using BD. All my pressure spikes came with magnujm primers.
