New Powders… Barnes & 6.8 implications?

This morning I read on The Firearm Blog that Hornady Superformance and LEVERevolution powders are coming in 2011.

The ammunition brought to market is interesting because it brings 100-200 fps more but still within SAAMI pressure specs. TFB has some hard data and graphs.

So what I wonder is…

Barnes Bullets like velocity. Generally speaking, the faster you can push ‘em, the more performance you’ll get out of them. So if these new powders can get 100-200 fps more, what tangible gains could we see in driving those Barnes bullets?

Now, the 6.8 SPC was designed to be used out of rifles with shorter barrels (e.g. 14.5″, 16″, even Bill Wilson typically uses an 11″ to take feral hogs). These powders are about efficient burn:

They achieve this by developing a set of new powders and blending these powders specifically for each cartridge so that all the powders burns completely inside the barrel. This allows maximum power transferred to the cartridge but also lower muzzle blast, thereby reducing recoil.

So these powders in short-barreled rifles… could use of these powders “negate” the velocity loss you see by taking a couple of inches off your barrel?

Then, Barnes Bullets that like velocity, easier to handle SBR’s, powder that gives you more velocity (and less muzzle blast and less recoil and more efficient burn) well…. could this be a fantastic combination?

I’m really curious.
