I was thinking a long loaded 357 Sig loaded with 35 Rem bullets and 357 pistol bullets would be cool and a subsonic option for a 6.8 SPC platform with a barrel swap. Just load till the bullet touches the mag rib in an AR15
What to call it?
35 Raven?

3,578,654,432,987.346778 boring
Sorry. Not interesting to me

I figure about 357 Maximum performance
Could be fun for plinking or hunting with a barrel swap.

6.8 case equals 30 and 35 rem case, improved.

Great. Just reinvented the 35 rem. some ideas would work but aren't worth the trouble

Then why did you post?

Anyway, I have a contender barrel chambered in 357 Sig, and it's got a pretty long throat and a 0.357" groove diameter. It shoots .358 bullets fine, and is actually less accurate with .355 bullets. I've played around some with the 180gr hornady and the 225gr sierra. There's not much case capacity with the 225, but if you're going for subsonic then you don't need much. I've tried some cast stuff and even paper patch, though I'm finding you really can't push lead very hard. A medium/light load with a .358" 162gr cast bullet works well at the local cast bullet silhouette matches.

With the heavy bullets you have to watch the brass you're using. Some brass is much heavier than others and will have significantly less capacity, so the load will be different. With a semi-auto I think you'd want to find a load that is compressed. That helps keep the bullet from being pushed deeper in the case when it's chambered (which can cause some problems).

Have fun!

Thanks for the info. Wildcats only appeal to 1% of shooters and then wildcatters might like only 10% of those so a wildcat idea might only appeal to .1% of shooters. I don't mind El Jeffe not liking an idea of mine. Odin knows I come up with a lot of bad ideas. I thought this could be a cool 6.8 platform cat. Maybe make it longer with 10mm brass perhaps. Though the 357 Sig to use the K.I.S.S. principle. Short range cheap 357 pistol and 35 rem velocity envelope is a bonus. I like to throw out an idea and see how it can become better with the experience of the members here. I think a "35 Raven" would be cool.

Hi El Jeffe. 25 and 30 Rem I think you mean. Yes on a different platform. The advantage of a 30 version that I have already posted on before is that the 30 cal would be the same diameter as the neck thickness of the 6.8 and be a pretty potent round being able to be a a bit shorter than the 6.8 but not much gained over the original. The 35 Gremlin does a great job reproducing 35 Rem velocities in an AR15 and that is pretty cool IMHO.

Why post? 1 boomie and I are IRL friends. 2 boomie sometimes has good thoughts. Sometimes crap. 3. This a a boring concept and does nothing "new". 9x39 tada 35 rem. tada

4 There is no market niche
5 well. It is boring

Just because you could doesn't mean you should. This isn't one of his better ideas

I haven't had a good idea in some time now. (.358x41.) Caught a lot of fish though yesterday! roger

I don't think I've ever seen one of those. 40S&W brass on the other hand, is everywhere. I think this idea has merit from the price/availability of components perspective. That's one of the reasons I like the 357sig anyway. It shoots 9mm, .357, and .358 bullets... brass is super easy to find, and it has plenty of oomph for a pistol round imo.

It would perform like the 30 blackout but use pistol components and that is kinda fun. The 180 grain hornady spire points could be the perfect bullet for this. Load just to the neck juncture and should clear the mag rib for max useable powder room. I can see a benefit to make a longer caliber length neck for max case capacity and pistol bullets.

The 30Rem is unless I'm greatly mistaken the original parent case for the 10mm auto and by extension the 40S&W (with small primer pocket), 357Sig etc...

It is also the parent case for the 6.8SPC

The 35Rem OTOH is a "fatter" cartridge

But the 30Rem and 35Rem DO NOT have the same case head diameter...

The 30Rem is basically a rimless 30-30 I have actually made 30Rem cases by lathe turning 30-30 brass, I made 100 cases for a friend with an old Remington pump rifle

If they do away with the stupid restrictions on suppressors that we have it might be a lot more interesting option.

I own a 357 sig (Custom converted 40 cal Browning Highpower)and while it has good velocity with lighter bullets, it doesn't get close to 357 mag with heavier bullets.

The 357 sig is not a strait neck down of any cartridge. If you neck down 40 S&W the neck is shorter than spec for 357 sig. If you neck down 10mm brass, the neck must be cut back to 357 sig length. A better alternative for your needs might be the 9X25 Dillon. It has more capacity / velocity and is a strait neck down of the 10mm.

Another thing to consider is either cartridge will be very short in a 6.8 SPC magazine. This means they will have a large jump to get to the chamber. Lots of bad things can happen in that distance. (Most pistol conversions have a block that goes in the rear of the mag well so a shorter pistol magazine sitting closer to the chamber can be used) I suspect you would have a lot of misfeeds in an AR-15.

Good luck
