IMR 8208 XBR
« on: February 20, 2011, 12:02:29 PM »
A friend was just telling me the story of this powder and I was wondering if any of you guys have tried IMR 8208 XBR?
Looks like a great powder for the .223 and Boise Sportsman's has it in stock.

Hodgdon Releases Impressive New IMR 8208 XBR Powder

Hodgdon IMR 8208 XBRHodgdon Powder Co. has unveiled a brand new powder, IMR 8208 XBR. From early reports, this is an exceptional new propellant that may change the way the game is played in short-range benchrest. According to Hodgdon, “IMR 8208 XBR is a remarkably advanced technology propellant” formulated for popular match, varmint and sniper rounds, including 223 Rem, 308 Win, 6mm PPC, 204 Ruger, 6mm BR, 22-250 Remington and similar calibers. We’re told the powder is being produced by ADI in Australia.

IMR 8208 XBR is Consistent in All Conditions
This short grain extruded rifle powder exhibits exceptional stability with virtually no change in velocity at temperatures ranging from -40 degrees F to 165+ degrees F. Lou Murdica, who helped develop this new powder, confirms that it is not temp-sensitive. Lou told us: “I have been shooting IMR 8208 XBR for over a year and I have done a lot of winning shooting it. One of the great things about this particular powder is, I always shoot the same load whether I shoot it in Florida or Phoenix AZ. I have never had to adjust for temperature or humidity.” That’s big news in the short-range BR game. Currently, most competitors must tailor their load to suit conditions.

IMR 8208 XBR is Already Winning Matches
Lou Murdica, one of the nation’s top BR shooters, won numerous matches with 8208 XBR in 2009, including the Heavy Varmint Grand Agg at the Cactus Classic. In August 2009, Jim Carmichel won the Heavy Varmint Grand Agg at the IBS Group Nationals. What is significant here is that Jim shot the exact same load of IMR 8208 XBR both days to win the event. That’s right–this powder requires far less “tuning” than most other powders currently used in short-range benchrest.

Product Development and Performance
Lou Murdica revealed some interesting facts about IMR 8208 XBR. Lou explained that the development team was initially trying to produce a propellant that would match the desireable characteristics of the “classic” T32 powder from the 1960s. In the process of developing a T-Powder clone, Lou says that the Hodgdon/IMR powder wizards came up with something even better: “We were originally pursuing a formula like T-Powder, but we came up with something a bit different. It was so good, and shot so well, that we didn’t want to lose it. It turned out that this stuff shot as well or better than the earlier T-clone mixtures and was incredibly stable.”

Lou MurdicaLou continued: “I’ve shot a lot of T-Powder and it is sensitive in certain way. I feel this new powder is equal to, if not better than, a T-Powder clone because 8208 XBR is not sensitive. I can shoot the same load, at any location, in any temperature or humidity. Additionally, and this is very important — the new powder is very forgiving. It has a very broad accuracy window. If you’re shooting 30.0 grains in a 6 PPC successfully, we found you could go down to 29.8, or up to 30.2 and the accuracy was still there. You won’t see a change in group size. It has a very wide and forgiving load window.”
[CAUTION: These charge weights may be excessive with your rifle and your bullets. Always start 10% low and work up.]

The new powder is versatile and has plenty of energy. Lou tells us “8208 XBR is a great powder. With a 6 PPC shooting 68-grainers, I can get up into the 3500 fps range. And the powder will work with larger cases too. I’ve tried it with success in a 6BR with 105s and I think it will work in a Dasher or 6 BRX. I also shot it in a 22BR successfully.”

Lou predicts that IMR 8208 XBR will have a big impact on the Benchrest game once it is widely available: “Once this powder gets in people’s hands I think you’re going to see GREAT things. It’s not finicky. It meters really well out of normal powder measures. It’s really stable. There are plusses all around. We’ll know within a year whether it becomes the powder to beat.”

Lou is no longer involved in the sale or distribution of IMR 8208 XBR: “I’m not in it any more. I have to buy my powder like everyone else.” But he encourages all BR shooters to give it a try: “The powder is fantastic. I have been telling everyone to go to your powder dealers and order it. Buy a jug and shoot it.”

Lou has high praise for the folks at Hodgdon: “You can’t say enough good things about Chris Hodgdon and Hodgdon’s willingness to develop this new powder. They’ve finally given us something we’ve really wanted and really needed. What they have done is great.”

I want to try some of this in my 308.  I use varget now and the thing I like about it the most is how well it works with bullet weights from 110 grn to 168 grn.  It will be interesting to see how this stacks up against varget.

From what I read the velocities are lackluster but once you establish your load you can expect that load to shoot the same regardless of temperature, a big plus for all the competition shooters.

I've shot it in both my .223 and .308....best group to date was a 1/3" 5-round group at 100 with my .308.  42 grains behind a 175gr Match King. :D

Did you chrono it? If so, how fast and what barrel length?

unfortunately I have not as yet....hopefully the next time I'm out at the range I'll remember to bring my chrono. :)
