Hodgdon 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 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.”
Product Availability — IMR 8208 XBR in Short Supply until 2010
IMR 8208 XBR will be available in 1-lb canisters and 8-lb kegs in 2010. Hodgdon has produced limited quantities already, and you may be able to find some 8208 XBR at popular vendors, such as Powder Valley, in early January, 2010. You’ll need to call around to see who has it.
 
Don't worry, too fast for what we are after :)

Hodgdon has posted some load data for a variety of cartridges and it definitely favors the light bullet or small case.

Ironically, velocities were not much better then standard powders. In fact, some examples were slower. All were loaded to SAAMI specs so there is room to hot rod.

I would love for someone to put a strain guage on the PPC loads they are talking about and see just how hot it is.

I am waiting for the super sized Re15 that will hopefully be developed in the near future. Same tech as the Re17 but in a faster burn rate ala Varget.

Ive been using it in 223 and 338F, works great. Will try it in my new 308 too. My boss uses it in his 300WSM as well with lighter loads
 
I still have 3# in my cupboard from the Kamloops Gun Show, I am waiting for it to double in price and then flog it for a 100% Profit. :D
 
And would you know of a store that might happen to have some in stock ? ;)

should work well in high velocity 303 loads with 150 grainers too :D and yes I know where there is some, currently $29.99/lb. Shipping approx $15 for 2-3 lbs
 
My .308 with 44gr of the 8208 and the 155 Berger VLD, is a match made in heaven. The only other powder that I have tried that is close in comparison for groupings is the H4895.

Hi Wildfowlhunting, have you been able to chrony the load? can you also give particulars of your rifle. barrel length, twist.?

I have a Styer SSG P2 in .308. The barrel is cold hammer forged and shrunk into the receiver for a barrel length of 26". The twist is 1 in 12 with 4 grooves. I was fortunate to be at the range when another shooter was using her chrony, she was kind enough to allow me to test mine. The shot was chrony'd at 2887 FPS, and that was with the 8208. I have not chrony'd the H4895.
 
I figgured I would revive this thread.....

I read an artical in Gun World Magazine (Dec 2010). He had favorable results with XBR in .204 Ruger, 22-250, 6mmBR & 308.

From -38f to + 90f the writer saw very little differance in velocity and no noticeable increase in group size. He did state that some of the velocities he saw were a bit slower than some other loads he has used, but all loads were consistant despite huge swings in temps tested in.

My self I was thinking that I wouldn't mind giving up even 150 or 200 fps if I had a load that would work from -25 to +30 c........

Hogdons web site has loads for all the rifle cal I have in my safe, I was thinking I should pick up a lb or 2, see if it lives up to the hype........

Has anyone else had any luck with this powder?
 
I have some sitting on my shelf but haven't been able to give it a go yet.
Some guys have had good results with it in their 6xcs which is where I will probably give it a shot.
 
Ive only used it up to 60 grainers in my 223, will try it with 77's when I get some.

Im going to also try it in my new 17 Fireball (aka Mach IV). It worked great in my 308 and 303, wonderful powder IMO
