Accurate 1680 uses

I've used 1680 in 300 Blackout. I reload a few other cartridges that 1680 is suitable for but I do not remember off hand if I tried it there. I've slept a few times since I last looked at my reloading records.

Here is a link to Western Powders reloading data Ver 7.0. Before each section, pistol and rifle, they have a chart showing the powders and what cartridge they are used with.

I use 1680 under 220gr Maker Bullet in 300 BO for a exceptional performing expanding subsonic load. Hitting armadillos with them sounds like hitting a truck tire with a hammer.

It's pretty much what I consider a very heavy magnum pistol powder.

I have used it in the .357 Max with good results. I'll bet it would be good in the 350 legend and some other straght walled magnum type cartridges. It produces a hefty fireball in shorter barrels.

I bought 2lbs for use in 45-70Govt.

The beach ball sized fire balls this stuff produces from a 22" barrel was quite comical.

The blast and blinding, flinch inducing fire ball was too much for me. I still have most of the 2 pounds and have never found another use for it.

I have 8 lbs on the way. It's a really decent powder for the heavier bullets in 300 Blackout.

I use Accurate 1680 in my 7.92x33 AR-15 the fireball is impressive but the speed and accuracy is too good to try anything else.

I purchased the 1680 a while back (8lbs of it) for my 375 win (Favorite for hunting),Usually load the Rl7. Also use for the 357 maximum. FPS is great and accurate enough.
Acquired a 223 Barrel for my encore in a trade (Groundhogs!), found some load data Accurate had from back in 2003..... Does anyone have accuracy experience with this powder and that Caliber. I know! it’s not the normal use for it. However, load data from manufacturer is what I have with mucho amount of the powder. Thanks for informing.

I have that same manual from back when I tried AA1680 in a Mini-30. I didn't get good accuracy with it, mostly because I was such a rookie that I was using .308 projectiles instead of .311 or .312. I suppose I should be grateful that I'm still alive.

I do have almost 2,000 grains left and was planning on using it up on some plinking fodder for .223 Remington. According to the manual, that'll be enough for 100 rounds of safe loads.

Try some in your Encore and let us know how it works.

1680 works real well in the medium capacity cases with larger caliber bullets from 32 to 45 or so. It also does well in an AR.

You should be able to run a search on the powder itself on the Hodgdon site as they now own Accurate powder:

Guys... Thank you for being cool about info. This is my first post. I anticipated “ That’s not in the updated manuals, therefore your not being a safe person during reloading”. “You need to look for another powder or how long have you been reloading”?
Point being..... I’m safe, very cautious been loading for years and have data from manufacturer. Glad to see a response that isn’t a gang attack for a question that isn’t the norm. Love the highroad , been reading a long time.

Oh and I looked at The link provided, and 1680 certainly isn’t a option when the 223 c add liber is selected.

It unfortunately has a sort of narrow band of good uses. I have used it mostly in 7.62X39 ammo myself. Did not like it in .22 Hornet at all.

Works good in 500 Magnum also. I've burned a lot of 1680.

Can be used in 7.62x39

What what information I have, it’s not the best for 223. So perhaps I’ll look to trade it for something that is. Thank you to all who responded.... Wish I could Het more “good” response for 223 use. Please continue to respond with info.

And Obviously I should take time to spell check

I'm assuming you got the 7.62x39 brass to reload eventually?

1680 is one of the best powders available for 7.62x39.

Try doing a search for "best 7.62x39 powder".

Just sayin'...

223

I use it for 357 max, 375 win and want to use it for 223

Welcome to THR!

Sorry, I was actually replying to the OP.

Didn't realize this was an almost year old thread...

www.loaddata.com shows some 1680 data that runs a 55 gr. FMJ almost 3000 fps from a 24" barrel.
