Thread: .308 and Superformance

A good mate has recently bought a Ruger .308. Its a long range tactical thing that weighs a ton, and pretty sure they come with a short 18" barrel so he wants to try and squeeze a bit more velocity out of the short barrel.
So this is where Superformance comes in to the discussion .
Just wondering if anyone has had any earth shattering results with a powder/projectile combo out of a .308

I think you will find that the Superformance Powder that you can purchase is not the same as the factory Hornady Superformance rounds are loaded with. I looked into this a few years back and came up with this from the Hornady/Hodgdon sites, and still current today.

What calibers can I hand load or reload with Hodgdon Superformance powder?

Hornady started loading the Superformance line of ammunition in 2010. Hodgdon followed up with the introduction of a Superformance powder available for hand loaders. However, the one Superformance powder that Hodgdon sells is not usable in all rifle calibers. Like all powders, it has a particular burn rate and will work great in some cases, OK in others and should not be used in the rest. A hand loader wouldn't think of using Varget or Retumbo in all their calibers from 17 Hornet to 375 H&H. Neither should they think of Superformance in that way.

Hornady uses commercial-grade Superformance powders of varying burn rates and also blends powders to offer a full line of Superformance cartridges. The Superformance powder that Hodgdon sells is one particular burn rate that does well in some short magnum cartridges along with some others, which are listed in their load data and also in the latest editions of the Hornady Handbook of Cartridge Reloading.

And this from the Hodgdon Site on their Cal recommendations for the 1 type of powder available to the general market

22.250, 6mm c/moor, 243wssm, .25wssm, 6.5 c/moor, 260Rem, 280Rem, 3006, 300RCM, 300WSM


Doesn't mean it won't work though!
