So I got 5 pounds of 8208 XBR from a friend that moved and I really don't know what to do with it.  I load 223, 6BR, 300BLK, and 30 carbine. All but the 6BR are for gas guns. I am planning to buy one of the new DPMS G2 308 rifles soon so I will be loading for that too. Looking at my loading books, I don't see where It would shine. It seems kinda fast.

What I'm asking is, does anyone use this powder and if you do, what cartridge and what kind of bullets are you using. Powder charge would be nice to know too to give me an idea where I might end up.

I have never used it personally. But the IMR website states it works great in 223/5.56 and 308. They talk about tack driving and extreme accuracy. Especially in varmint cartridges. So why don't you try it and see if it lives up to the hype? The people I know who swear by it load it in .223/5.56. If it doesn't then sell it or trade it for something else.

On the interesting side it is very close in burn rate to one of my all time favorite powders which is H4895. It should work well in a variety of cartridges.

Thanks inspector,
I read some of the same stuff as you about it but couldn't find any people who actually use it for 223 in an ar-15 and working up loads living in ewa and shooting at koko head is inconvenient.

Looks like I already have an offer to trade for some cfe 223 that I already have developed loads for. 

I've read that 8208 was the powder used in Atlantic Arms 77s shot by the All Guard team and the AMU? I have clocked the AA load at about 2800 ~ 2900 fps - which I can't duplicate safely with my fave powder - RL15
These are some results from a shooter from nationalmatch.us:

I can't remember if the AA or Mk262 had crimped in primers

Everything happens for a reason. 

Ive used it for 6br and 308, bolts only though.  If you don't want it let me know.

I have H338 maybe we can work out a trade?

Maybe it was 335?  Ill have to look.  It's for .223, which I don't load for.  Lol

I think you mean H335. Which I happen to find gives me excellent accuracy with .223/5/56. 

Thanks for the responses everyone. I will be trading it for CFE223.

It looks like 8208 shines with heavier bullets  in 223. I prefer light bullets as I don't shoot long enough range to take advantage of heavy bullets. As for 6BR, I have almost 10 pounds of varget and it works great under 107 grain matchkings.

with 8208, my tightest groups were in the range between 25.6 to 26.0 grain.  I'm using NATO brass and Hornady 55 grain FMJBT.

This might be a little hotter than some of the loading data, but i worked up .2 grains at a time from 23.6 and keeping an eye out for signs of pressure.
