From a press release:

New Powder for 50-Caliber Applications
In 2009 Alliant first announced Reloder 50, a new powder designed for long-range, 50-caliber rifle shooters. Though it still has not reached dealers’ shelves, the powder looks promising. According to Alliant, the burn rate is “a little slower than Winchester 860″ and the powder is showing excellent lot-to-lot consistency. Load density is optimized for the 50 BMG and similar cases. Like Reloder 17, Reloder 50 employs a process which penetrates the kernels with the burn-rate-controlling chemical. This should allow a longer, flatter pressure curve, allowing more velocity than conventional powders can deliver. Alliant says that Reloder 50 offers “superior velocity and the ability to burn cleaner (with less residue).”

Thus far, this new powder has not entered the distribution chain. 50 BMG shooters have been waiting a long time for this new propellant. However, Alliant tells us that it hopes to start shipping Reloder 50 before the end of the year (2010). Reloder 50 will be available in both 1-lb (#150527) and 8-lb (#150528) containers.

I'm not a .50 BMG shooter, but this powder should have potential in calibers like .264 Win, 7mm STW and Ultramag, and .30-378 WBY. Will be interested to see some data when it finally hits the market.

It might be a little slow for the .264, but it will be great in the 7mm STW and the Ultra Mags. I shoot alot of WC860 in my STW, so I too will be interested in seeing the data.

I'm thinking it may be used in my 270 Allen Mag.

I guess the 1 lb can is just a sampler to figure out if you want to load more than a few rounds.

Stonecreek ----- Thanks for the heads up, I shoot a lot of allient powders. Sounds like the new powder would be perfect for the .270 WSM's. Good shooting.

Then I guess it would also work well in the 300WSM?

With an equal sized case, the one with the smaller caliber will require a slower powder. If it's just right for the .270 WSM, it would be too slow for the 300 WSM.

Personally I think with will be too slow for either of the WSM's. It should be better suited to the RUM's.

shhhh... don't be so aesoteric as to mention slower powders may mean higher velocities ... you'll get some folks dander up telling them that slower burning powders change the repssure curve ....

ah, wait, who am i kidding? one just has to look at a reloading book to know this one!


btw, 50bmg powders may be too slow to work properly in a dinky little wsm ...

Is this available yet? If so, has anyone here used it?

Grafs lists it as in stock.

In a 264wmag QL calls it basically gr for gr with H870. Both in the top 4 as to velocity potential.
