6.5 creed magnum

I wonder if it is going to make it to straight wall cartridges? Getting a couple hundred "extra" fps out of a .350 would be a real benefit.

Based on what the gentleman from Federal says, a +peak for the straight wall crowd could get interesting. I have to hunt straight wall in my home state and I wonder how the lawmakers in those states would react to a +peak straight wall (350L, 400L, etc). I’m not a ballistics expert (or even that knowledgeable) but it seems like those calibers could benefit from the tech.

Same thought at the same time!

What doesn’t make sense is he says it’s the most popular calibers form the last 15 or so years, yet no belted cases and no cases larger than 3006/308 head diameters, that narrows down fast. Now add to that they’re lookin at larger cals so that’s not much to choose from.

I think that's more about the technology apparently relying on a narrow powder column. I wouldn't anticipate it being used for magnum bolt face cartridges for a long time without a design.

Yeah I think a 556 is already done if I’m not mistaken.

It will only work if the +peak doesn’t up bolt thrust. All the straight walls in AR’s are bolt thrust limited, not brass pressure limited. Almost every one already has a bolt only load with more pressure already.

I can see how an action that will handle a mag bolt face can handle more pressure on a 473 bolt face. The bolt thrust is pretty close between those two if case friction is similar between steel and brass.

I'm not sure that is actually the case.
