Accurate 1680

[kvd]

I've never used this powder before and can't believe how finely ground it is. It seems like dust compared to the powders I'm familiar with. Is this the nature of this powder? I have lot 0527202110.

Yes, but it's very limited in rifle application. Really fast for most rifle cartridges.

I use it in my 300 BO.

 

[SmokinJoe]

Good in 300BLK w/125 gr bullets, K-Hornet & 221FB w/40 gr bullets. You want some real pixie dust, check out Alliant 300MP.

1680's a dandy in the 357 max as is the older WW680

Thanks for the responses gentlemen. This is for a 300 AAC Blackout.

 

[Dan Calhoun]

It was designed as a copy of the 762/39 powder that the AK and the SKS used. Works well in those rifles

Yessir, 1680 is a good one for BLK and it's also the best powder I found for the 17 Ackley Hornet.

1680= very good in 762×39/ 110 grain bullet's/ 308 bore.

I use 1680 in 357 Max and 445SM. Weeeeeee bit of muzzle flash in the 445 SM

Good to know. I have an AK but have never loaded for it - always have shot the steel cased 7.62x39 from Russia in it. Thank you for the info

Just a little muzzle flash - barely noticeable!

What is a 445 SM? Looks to be pretty stout.

445 Super Magnum is a 44 magnum case that has been lengthen by 3/8 inch. It was Designed by Elgin T. Gates for silhouette shooting. I’m shooting Hornady 240 gr XTP’s @ 1850 FPS. Son asked if I could shoot one at dusk sometime. Need to do that sometime.

That’s a bigger flash than I get when I light a fart.

Yes, AA 1680 is a fine grained powder that meters exceptionally well. I use it for subsonic rounds under 220gr Sierra MK’s in 300BLK and 500gr Hornady DGS/DGX in 458 SOCOM.

I have found, at least at subsonic velocities and shooting suppressed, it tends to be a bit dirty.

Your ak has .310 bore. 1680 is still great but you will be stuck with 123/125 bullet's only.

 

[kvd]

Your ak has .310 bore.

That fact is definitely something to keep in mind if reloading for the AK - 0.308 diameter bullets are not compatible with the 7.62x39 bore, which probably explains the existence of 300 AAC Blackout in the first place.

Years ago, Accurate Arms had in their manual that 1680 was THE powder for a 221 Fire Ball, I shot a lot of it.

 

[kindabitey]

For the 300BLK, it's the easy button. It's one of the original powders used for it. The downside of 1680 is that it's dirty and loud (suppressed) compared to the vast array of other
acceptable powders.

AA 1680 is practically the same as the "discontinued" Winchesster 680. So, if you have old manuals, you can use that data.
Just don't think they are ideal for low-pressure cartridges
