Looking at the brass, I was thinking of opening up the neck and making it along the lines of a 38-55 short for use in an AR15. Looking on my shelf, I saw a set of 357 Herrett dies and thought that this might be a good cartridge too, for the AR15. A 357 Herrett rimless!!
Might work better because of the front rib in the AR mags might interfere with the 38-55 srl (short rimless)
Anyone got a 357 Herrett reamer laying around that I could use??
No, but I'd be very interested to hear about the results, and whether it fed or not. I like the idea a lot. Biggest problem I can see is the .30/30, on which the Herrett is based, is significantly larger than the .223. IIRC (probably not) the dia. of the brass at the head is something like .422???? The .223 is @ .378 from my faulty memory, so correct me on this if I'm wrong. This would indicate that what you'd probably want is a .35 cal. on a max. length case for whatever bullet you intend to shoot. You'd probably have to work backwards from the bullet length and crimp groove placement of the bullets you want to use. This should give you your best "ideal" case OAL from base to case mouth. Simply cutting off .223's would likely work, when sized appropriately, I'd think? Very interesting idea. I can't recall where, but I think this has been experimented with before somewhere??? Maybe someone here remembers?
Open it up to 35 cal and I'm interested. I've had my eye on the 358 Yeti for awhile now. But lack of barrels and dies has me looking elsewhere at this point. I like easy brass conversions so simply necking up the Nosler case is quite appealing.
This is close...https://www.nosler.com/33-nosler/Originally Posted by dragon813gt
Blackwater---the 22 Nosler is .420" at the base vs .422 for the 357 herrett. Could send an AR barrel to JES for a rebore, as long as its not chrome lined!! Have already necked a case up to 35 cal and run it thru my 357 herrett die. I think it will work fine. Now, to find a 357 herrett reamer.
Necked to 7mm, then 30, then 33 and finally to 35. With a good taper expander, I am sure you could do it in one pass.
20 nosler?
i luv the 20 vartarg(221 rem fireball necked to a .204" bullet), i'm just wondering what a 20 nosler will do?
Close but not there. I've wanted a 338 Federal for a long time. But I don't want to invest in new molds and all the other tooling. I'm completely setup for 35cal already. Would just need to build the upper and have at it. In reality I don't want to mess around w/ a proprietary case like this. That's what's made the Yeti so appealing. At this point there are so many wildcats it's impossible to keep up w/.
Maybe a modified Herret on the 7.62 X 39 case would work better. Neck up the 7.62X39 case to 35 cal and blow out some taper. Save a lot of case trimming ( a 1/4" has to come off the 30-30 to get to Herret length).
Country gent--22 Nosler is 1.76" long vs the 357 herrett of 1.765". Plus you get to use your bolt from the 223 as it has a rebated rim like the 284 win.
Okay misunderstood you first time, sorry. That's should work out well also. Will it have enough shoulder to headspace? and enough body taper to eject feed reliably.

Statistics show that criminals commit fewer crimes after they have been shot
Would be a 35 Remington!
357 Herrett without a rim is just basically a 35 Remington, take a look at the 35 Rem.

I made a 357AR 357Max Rimless from 223 cases, but that 22nosler looks to be a great base for a .358" bore. The extra case taper would help in feeding and gain you some speed. The only down side would be the price of brass and reloading dies which really aren't a deal breaker, just another step to take. I had looked into using 5.45x39 brass as the parent case and making a die set, but went with the much cheaper and easy to find 223 cases and 357mag/max die set. I'm in a shotgun or straight walled cartridge zone for deer and I'd bet others would be interested in it as well.

Howdy !
FWIW -
Shortened .35 Remington cases can be necked-down and case formed to make a rimless " .357 Bain & Davis ".
I DK how much trouble the rim diam might be, in an AR format ?
.357AutoMag has the same case capacity as a .357 B & D, or a .357Max. Rim diam would be a little larger than
the .35 Rem's.
With regards,
357Mag
357AMP will only get you about 2000fps in a 20" barrel with a 180gr SSP before you hit 40K psi which is about it for a .473" case head in an AR15. You can hit 2300fps with a Max-rimless using the same bullet and keeping it under 60K psi. I wonder what the case capacity of a 450BM necked down to 357 would be? You'd still have to keep the PSI under 40K but at least you'd have a lot more case capacity.

Seems obvious to me, but a short action bolt rifle with perfect brass for the 311041 is a no brainer.
