6mm creedmore + Peak

I would love nothing more than to see a 6CM steel case hit 6UM velocities. I hate every part of reloading. But little birdies keep telling me the accuracy isn't there in these Federal cases.

I have been wondering about the accuracy of these

Think that’s a product of the pressure?

Seems like their SD have been low on the velocities.

Possibly, I would bet neck tension plays a part. But that's pure speculation on my part.

Yeah, I don’t recall much/any of the Guntubers with early samples showing off their groups.

I would love to see this tech adopted in some of the cartridges that would pass the lawyer test. Yes, the .308 Should be able to handle the same treatment as it is the case itself taking the brunt of the additional pressure but there is no way lawyers are letting 50-60 year old rifles shoot this stuff. I do think a .338 federal with this case would make about the perfect knock around Alaskan do it all gun, a handy short action 35 Whelen AI.
Take the 350 legend and this tech and you have a 348. A 450 Marlin and you have a level gun stopping rifle. It is interesting to see where it goes with existing newer cartridges that never really gained traction or brand new efficient cartridge designs.

JVB did in his video.
I'm hoping to be an early adapter. Just ordered a new 6 creed with a 20" barrel (will be getting chopped further) today specifically to try this idea out. Worst case scenario I still have a new 6 Creed.

Proof showed a stellar group on their review. Related, it seems like we’ve seen plenty of 7BCs now that shoot well.

Federal is saying the case should not be necked down.

While it may be physically possible, it might be unsafe. I definitely would not want to be holding a rifle with 80k PSI if something goes wrong.

There's already overpressure rounds that can't be shot in older guns. 45-70 is a great example. You cannot take some of the buffalo bore or HSM stuff and put it into a rifle from the 1800s designed for black powder.
+p+ on pistols, etc etc. So this isn't exactly new from that perspective.

You could do the lever gun cartridges, but you'd have to shoot them from bolt guns, which are rare chamberings. There's a reason those cartridges are at such low pressures already. The action cannot handle the 65kpsi that a brass case absolutely can handle. It's why you can't rechamber a marlin or a winchester to the 460 and 500sw. Those both run at or near 65kpsi. Bighorn had to design an action for that. 460sw actually outruns 450 Marlin because of the pressure difference, despite less powder capacity.

I agree they need to do the 338 fed in steel. 338wm with a bit more recoil than 308win? Yes please.

I saw a bunch of cherry-picked content from pay-to-play influencers. I've been around two 7BC and was less than impressed. The steel 6.5 Creedmoor case should be a layup if it's the real deal. We will know very soon.

Can you elaborate on that at all? Any specifics on what might be causing the dispersion? Based on what I've read, I would believe it's inconsistencies in the sizing but I haven't played with any of the cases yet. I could see where volume discrepancies could be an issue as well. Didn't know if you had additional info you could add.

The skeptic in me thinks this is all bullshit but the optimist in me would really like this to work for obvious reasons. Either way, it's cool to be here at a time where there could be meaningful revisions to what we know about cartridge cases. The hard choice is going to be when it turns out you can't reload them and get the performance you want but you have to buy it preloaded from the factory. I know where I stand on that but I think there are plenty that would be perfectly content with that.

Agreed, I'm not putting any stock in the influencers. But Proof posted what appears to be a sub 0.5" 10 round group. Obviously they have some skin in the game here so perhaps not the most reliable source either.

I'd consider myself a 7BC hater/skeptic... That said, there are have been good accuracy results posted here on the rokslide forums from very reputible members...

Any chance you can elaborate on your sources. No offense meant but "little birdies" carries about much weight as pay-to-play influencers.

Not quite. Little birdies make money off selling rifles; they don't care about cartridges, as long as it's accurate. Can you say that about pay-to-play influencers?

Maybe, but we're only 3.5 years or so from the next ammo shortage.

 

[Pilsner]

One of the testers/paid shills was saying that the ammo they got to test was specifically NOT to be used for accuracy testing due to not being what is going into en mass production. As per Federal.

This assumes that whomever it was talking (John Snow at OutdoorLife IIRC) was relaying accurate info. Pun intended.

Meh, our parents told us all kinds of crazy shit not to do, most of us made it out of our teenage years.

 

[Treelineasassin]

Area419 did a video with a proof pxt barrel, high psi peak alloy 130gr ammo. 300y, believe both 5 shots groups were under moa, one was around half moa. Small sample size.

I will let others experiment. I fear ending up on the Darwin Awards. I would definitely take things too far.
