Powder less smokey and dirty than N320?

I'm using 5.1gr of N320 behind a 230gr zero FMJ, and I'm not all that happy with how smokey and dirty it is. I thought this stuff would be as clean as N340 in 9mm, but it's not even close. Is there anything better for pushing a 230FMJ to about 800 or so FPS?

I'd be happy to paypal you $10 for that N320 ;)

All kidding aside, everyone talks about how clean and soft it shoots.

I just started using it for .45 because I have about 12 lb.s of it and no longer shoot .40

I'd read the same things, and I LOVE N340 in 9mm. I can shoot 600rds of it and the gun looks like it was just cleaned.

It's soft, no doubt. 5.1gr gives me avg. 792fps w/ a 230gr bullet, but it doesn't feel like 183PF at all.

But as you can see, there's plenty of smoke for an FMJ, and it's not much cleaner than I remember Bullseye being.

It must be a .45 thing because I have never experienced smoke or dirtiness with N320 in 9mm.

Those fmj's will still smoke a little with almost any powder due to the exposed lead base.

Good point. Maybe I'm expecting too much.

My damn near smokeless N340 9mm loads were JHPs....maybe that's the difference.

I also use VVN320 with 230gr Zero bullets with no signs of smoke. I also use it in 9mm and 40 cal with no smoke with either. I have never seen anything like I'm seeing from your video. The Sierra reloading manual has loads up to 850fps using 5.5gr of N320, I've had no problem with any of them. You might double check your taper crimp.

Looks like I'll have to order some Clays to try next go around. I'm also thinking WST and good ol' Bullseye.

My theory is that at this hotter loading, the temp behind the bullet gets hot enough to burn off more of the exposed lead base than a lighter loading, thus creating more smoke.

But that doesn't explain why it's so darn sooty-dirty though.

Attached is a link to an article that debunks that theory regarding lead getting so hot it melts,it is a very interesting article . Follow this link, http://www.lasc.us/TaylorLeadingDefined.htm

Interesting.

So then, in theory, the exposed lead base of an FMJ should zero effect on the amount of smoke (or lead vapor). And all the OSHA studies about lead vapor are unfounded?

Not sure I buy the de-bunking there, given the amount of more rigorously obtained evidence about lead vapor to the contrary.

Man that video doesn't even look like N320 and the Berrys plated I've ran through my snubbie. Not even close. I can shoot 200 rounds through it before you can hardly tell it's been shot from it's last cleaning and at an indoor range I don't see any smoke. But I've moved onto cheaper alternatives. WST is a good all around pistol powder. Almost 1/2 the price of N320 and I use it in .45, .40 and 9mm. Going to try it in .38 special on my next loading session. Clays is always good in .45.

I ordered a pound of WST to experiment with for 45. I'll also be trying N340, since it's ridiculously clean and accurate in 9mm, and should give me the velocity I want without going anywhere near max.
