6.5 creed magnum

[kevingm1987]

Seems like the other creedmoors and arcs are ripe for this based on your post above.

Will be interesting to what is next. Would love a 6mm creed, but dont know if the demand is there.

Why magnum bolt face applications are less likely.

Any idea if a guy will be able to neck these cases down to 22 or 6?

Apparently they say they've got dies that'll reload em.

22 Creed with an extra 200 fps...

Or 6 Creed would be nipping at the 6 UM

I could put 200 fps from my 22 Creed to use.
Be cool if they did all the Creedmoor case’s with this tech.
Might as well while we’re here. Finish the job.

I think the demand is there, those that went with the 22 and 6mm CM did so because they wanted more
in the first place. Sales appear to be going up for those.

Bolt is limited by thrust. The case can not contain that pressure. It’s a function of the pressure, case head diameter, and friction from the case interacting with the chamber. Now steel cases may have more friction and that’s would reduce bolt thrust. I have not done the math to figure it out.

Now many of the “ pressure” tests we use as reloaders probably do change when the steel contains the pressure better. It doesn’t expand as much or stretch until exposed to more pressure. This could make bolt thrust worse or better as static friction is dependent on normal force. If the case doesn’t expand as much then friction may will be less and bolt thrust is more. If it expands more the friction will be more and less bolt thrust. I expect we will hear more as people start doing actual tests.

What’s your thoughts about the barrel, most use a basic soft 416, or 416r/416t, so the barrel has to also contain the 80,000 psi until release, so other than the obvious reduction in less barrel life could it be dangerous or cause any bulging.

I believe most rifles are thick enough that the steels used can contain the pressure. Also max pressure is basically at firing and drops from there. So only the chamber seems max pressure. To bulge, pressure would have to exceed yield strength, I don’t think under normal use 80k is above yield, but I have never done the calculations. Proof loads are 1.5 or 2x rated, so I think 80k has a decent headroom. Also my personal opinion is that people routinely get into the 70k range with brass when handloading for max velocity. So it’s not much if any jump of some hot handloads.

Now steel has a unique property in that it will go an infinite number of cycles if the load is small enough. Once above that loading, it’s a typical cycle vs load like other materials. A barrel has to go 2k cycles? That’s not that many, so you can probably be in the middle of that curve and still be safe. Quite different for a shotgun that might go 500k rounds.

This is probably the best advance in ballistics that I can remember in a long time and most of the posts here are bitching on the negative.

And complaining about the cost of ammo.

Literally spend thousands on rifles and gear, but the thing that actually does the killing, that’s a bridge to far as far as cost is concerned.

Everyone needs a louder Creed

If it hits the 6 CM I’ll try a box, but it will have to out shoot a lot of ammunition before I will spend money on it regularly.

Don't hold your breath, steel doesn't flow like brass so it will be near impossible to neck down peak+ cases at home. It would be interesting to know how Federal makes the cases, but that may be a proprietary process using drawing and swaging with immense forces, or metal injection molding.

We recently caught up with Concurrent Technologies to learn more about its latest advancements in metal injection molding (MIM) as it pertains to cartridge case manufacturing.

They legit? If so will preorder a bunch.

Yes I've bought rifles from them and ammo a few times.

Good to hear. Rokslide costing me money once again.
