Patent from Federal covering case design of the new 7mm Backcountry

[Petey308]

Here's the patent for anyone interested in a technical read, regarding the case/cartridge design used for the new 7mm Backcountry from Federal. This will provide way more info and answers than you get from a lot of the internet speculation out there right now.

Keep in mind what's in a patent isn't necessarily what makes it to the final product, or at least not right away. It protects them for options down the road though.

It does appear though that there may be much more to it than simply a case made from a steel alloy. If the primers are actually secured differently and the flash holes are different, it may make reloading even less practical or possible. If hand loading this cartridge requires significant extra steps or can only be done with traditional brass cases and loaded to a lower pressure than factory ammo, I'm not sure how popular it'll be. Sure, there's always the option of just shooting factory ammo, but I personally am not real interested in that. I'm also curious how you'd know for sure when your reaching max pressure working up a load with such a cartridge.

Time will tell and I'm very interested in seeing how it all plays out. I'm patient and in no hurry to rush this technology or completely dismiss it yet.

Us patent nerds thank you so much.

May complicate handloaders is an understatement.

As I said in earlier posts, until we see a case cut in half...........

Is it ornamental?

I quote Elon Musk when he talks about Patents are for the weak...

Musk has said that patents are ineffective and act as a barrier to innovation. He has described patents as "landmines in warfare" that "don't actually help advance things"

He freely allows anyone to access his stuff. Why? He says by the time the copy it and bring it out, he is 3 iterations ahead of it.

IMO, given what they are doing, this is likely not going to be an effective handloaders round. I dont think that is what federal was trying to do. once you start utilizing brass as a reloading component, physics takes over and we are limited to what we can do out of that case.

Some detailed stuff. This sentence reminds me of the gibberish found in turbo encabulator video.

"Moreover the concave shape when forced rearwardly during detonation of the primer propellant, urges the concave shape towards a flat shape and as this happens the diameter of the concave wall portion increases providing an outward radial force on the rearward corner portion of the tubular axially extending housing forcing the corner portion into the inwardly facing surface of the casing that defines the primer cavity tending to lock the primer into the casing wall securing the primer in the cavity."

Check it at the 2:50 mark for a sectioned case

This!

Likewise!

Check it at the 2:50 mark for a sectioned case

Compare 12:23 to a current 7 PRC with a 155 grain bullet

Assuming they are using some "magic powder combo" to get that velocity, is someone who hand loads buying all that stuff for 200 fps or 7.5% better velocity? Dunno - maybe?

For the first time LR rifle buyer who doesn't hand load - more likely perhaps
