Has anyone tried this powder out yet? I was thinking of trying it in my 204 and my 6.5x47 lapua. So if anyone has tried it let me know how it's working for you.

Haven't seen it here in WA state, yet. Please post results if you try it.

Weasel

Shooting Times Magazine February 2010 issue has test results on page 22 with IMR-8208 XBR powder.

.204 Ruger 26 inch barrel: I am assuming these are Max loads
Barnes 26 grain Varmit Grenade - 28.7 gr - 4,190 fps
Hornady 32 grain V-Max - 28.4 gr - 4,031 fps
Sierra 39 grain HPST Blitzking - 26.8 gr - 3,668 fps
Hornady 40 grain V-Max - 26.7 gr - 3,617 fps

.223 Rem with 26 inch barrel:
Nosler 40 grain Ballistic Tip - 26.6 gr - 3,437 fps
Sierra 55 grain HPBT Gameking - 25.0 gr - 3,084 fps

Good loading and shootin,

I don't know the .204 but those velocities with the 223 are no better than many other powders will do, are they?

This is not a velocity powder, it's an accuracy powder. It is a replacement (load data is not the same, though) for Berger's T32 and Thunderbird 8208 (both from lots of surplus military 8208 used for loading 5.56mm tracers) that was so prized by BR shooters for its accuracy.

From what I've found on it so far, it is producing some impressive accuracy without sensitivity to small charge variations, temperature, etc....that makes it a good candidate for BR because people are finding that they don't have to adjust the charge as the day progresses and temperatures change, and it meters very well.

The IMR-8208 XBR loads in the Shooting Times Article did state pressure of the loads. Accuracy was based upon Four Five shot groups out of Ruger Varmit and Target Models as follows:

.204 Ruger 0.52" to 0.83"
.223 Rem 0.46" to 1.05".
22-250 0.72" to 0.90"
6mm PPC 0.75" to 0.92".

22-250 with Hornady 40 gr V-Max and 38.0 grain powder 4,118 FPS.

6mm PPC with Sierra 70 gr HPBT and 29.0 grain is 3,134 FPS.

Good loading and shootin,

I'm going to pick up an 8# keg monday or tuesday. After I'm finished with predator hunting, I'll play with it some and see what I can come up with.
The new hodgdon reloading magazine has several write ups on 8208, if anyones interested. Thanks for the input.

I am looking. It looks like there may be some good loads to try in 308. I may look and see if I can find some.

I picked up some 8208 yesterday, so today I took off work early, and put some loads together.

Rem 700 vssf II 204 ruger 26"bbl. Started at 26.5gr and worked up to 27.4gr in 1/10 increments. Bottom velocity was 3590fps and top velocity was 3766fps. the first 9 rounds went into a 1" group, but the last one with a loading of 27.4 gr was about an inch to the right of the gtoup.
Loads 36.9,37.0 & 37.1, grouped into 1 ragged hole. So far I like what I'm seeing.

I'm using the sierra 39gr blitz king, remington brass & federal gm205m primers. I should have put in my previous post, but accidently left it out.

Hey weasel,

I just obtained a couple pounds so I'm going to start some testing of my own... I like the looks of the grain size.

Have you done any more testing?
