Uh did you not notice that while they do list it they also show it as "UNAVAILABLE, LIMITED PRODUCTION"?

I have been looking for some myself and Midway just doen't have it.

ref Midway.

Mea culpa.
I didn't go far enough....the unavailable doesn't pop up until one tries to order.
Very sneaky! 

I got cases a year or so ago when they first became available. 

Someday I will actually get the rifle built. FB J action with a GM barrel and CPA wood.

The rifle is a cadet. Since some people chamber them for 32 specials, it shouldn't be a problem with the max. I seem to have gotten the idea from people on this site with martins. I too have a 357 mag. I love plinking with it
The Jamison brass is new. Belim says the older Jamision brass sometimes splits. I thought I would anneal it
I'll probably buy some 180 grain Barnes and try them  if they don't do well I can shoot them in my 35 Whalen AI

True, but the .32 Spl, while long, is tapered, and that allows it to "turn the corner".

Made a couple of dummy rounds.  One with 140 grain barnes pistol bullet and one with 220 grain hot core lead rifle bullet. both make it "around the corner" when I tried them in my .357 mag martini.  Of course they don't go all the way in, but I am sure they will in the maximum.
JES is reboring with a 1 in 14 twist, I hope it works with the barnes 180 grain, if not I have to stick with the pistol bullet for hunting.
My lee .38 special dies resize the entire shell unlike some other brands.  The lee dies smash the soft point of the rifle bullets.  Next I'll try my .35 wheel AI dies to seat the bullet.  Hopefully these will work.

another option is 360dw. longer than 357 mag and shorter than 357 max. can use 357 max reamer and just stop short. the beauty of this is starline makes 360dw brass and it is avail. you can buy direct from starline. actually my h&r had such a long throat I did not have to ream.

corerftech,Last year, I had been looking at wildcatting my AR 300 BO by simply running a 300BO reamer deeper into the chamber, thusly it becomes a hotter round, particularly with 125 to 130 gr bullets for hunting. One can still use 223 brass and the std mag and bolt face. 
I found it shoots up to 200 gr cast bullets very well as is.
Then, since I am also a SS rifle affictionado, I recognized the 357mag and 357maxi have the same base dia as the 223.
So, I started forming cases based on the rimmed 357 m & MX brass.
So far, I only have some  bp capacity data on the rimmed 300bo variants. I have made some cases in various configs.   
1. Run 357 maxi case all the way to the shellholder touch into my 300 BO die. This makes for a long neck for long bodied cast bullets. Capacity is about 20 grains Swiss 3f to the base of the neck. Or up to 18 or so gr D4227.
2. Run 357 maxi case into the 300 bo die until I have about a
    0.275" neck.  This forms the case into a slightly short 30x223 size.  Capacity:  30 grains Swiss 3f to the mouth, 27 gr Swiss 3f to the base of neck. The longer, number 2 case with a 190 gr Lyman 311334 seated to just cover the grease grooves feeds into the 357m martini cadet chamber just fine. 
Actually, I could picture a person chambering a 310 cadet thusly. Based on the COW listed bullet dia for the 310 ctg, one could use 8mm cast bullets in this "310 Rimmed BO"

Looking at a Win LoWall, to maybe make one up.

Strongly consider the 30-30 Wesson.

Any 30-32 cal variant that can be based on existing die profiles and use existing brass that yields a quality wildcat for SS BP service is high in my book of projects. 
The fact that a sundry reamer, sundry dies and brass I have several thousand pieces of can marry with a 30 cal barrel and give me a decent little 150 grain bpcr is way way cool. 

Now it just needs to get to .323 for a 32 blackout and just about every Swedish rolling block worthy of canabalizing is game for a conversion. 

I have a new 27 inch 30 cal barrel that I have no desire to use as is (Krag)on the martini its presently attached, it's got a 6 inch full diameter shank and is an eAsy convert to this service. Would screw into a swede action nicely. Might even run some smokeless loads over the RSI and work up cast to 25k. 

Maybe it's even a breach seatable cartridge? There would be significant BP capacity increase. Maybe that's the 32 cal version! It would be straight walled, or nearly.

Anyway I think it's a huge opportunity for a fun cartridge with some flexibility and all parts are readily available. I'm kind of sick of scrounging for parent brass all the time and taking out a mortgage to do so. This would not break the bank.

Gun should be on its way back to me from JES reboring get as a .357 maximum. Have brass all prepared and ready to load. I still will need to bush the firing pin when it comes back.

The martini action should be plenty strong for the maximum. A strong action and the maximum is not to big in diameter

IOwnDoubles,

I have a Martini Cadet action chambered for 357 Maximum, and shoot 180g Hornady FTX, 158g plated round nose and 140g Hornady FTX.  The cartridge length does require the lever to be pulled down to full "extraction" in order to insert, but chambers smoothly.  Extraction of the empty cartridge is perfect.  NO MODIFICATIONS WERE REQUIRED ON THE BLOCK.

My best accuracy is the 140g FTX, with 16.5 grains of 2400, at around 1800 fps.  Pretty consistent 1 1/2 " groups at 100 yards and recoil is not too bad.  Good luck with the new barrel.

Any info on .357 Max is good for me, mine is close to done. 
When I get it I will let you all know how it does. 
22 1/2" barrel, a bit on the heavy side for recoil with 200-220 grn loads.
Built on one of the "thick" actions.

Dino in Reno

When the 30 Herrett got a mention I had to chime in. I have a little Martini in 357 Herrett and it is extremely accurate using the same load I ran in a 10" Contender. Power and accuracy in a little package and a heck of a lot easier to shoot. ratseye

I use the brass to size and trim for my 30-30 Wesson.  Didn't know it was hard to get ahold of.  I stocked about 500 rounds.  Do anneal your brass though.

I tend to agree with beltfed since some of the early data was on the hot side and some more than just hot. I used H-4198 and Hornady 200 grain 358's in either spire or RN for my 10" Contender in 357 Herrett. It was running near 1600 fps and was a handfull to shoot. I shot some in the BSA Cadet but ended up toning it down some. Still an underappreciated cartridge I think. ratseye

I have been shooting a 300 BO Rimmed since the late 90s. I had Virgin Valley make a barrel on a Shilen blank 1/10 twist for contender. This is a 12" bbl set up for handgun Sillhouette. Doing it over I would consider a 1/12 twist. The barrel shoots RCBS 165gr bullets at near max charge accurately.

I had 2 extractors made so I can shoot either rimmed and rimmless cases

Starline has 357 Max brass

I've shot the Hornady 200 grain FTX in my 357 Herrett BSA Cadet with excellent accuracy. Maybe slightly better than their Spire Point Interlock. Have not used it on game yet but planning a pig hunt soon. ratseye

nope
if it cracks, I pitch it into the recycle bucket

I heard that the 350 Legend is actually .355

built a 357Max on a BSA martini last summer ,19 1/2 barrel and is a bit heavy but does shoot nice with 180 rem and 19 gr IMR 4227

Now I know what I could do with the hoch mold I got years back. I ordered a .359 mold for a 357 and he sent me a 355-260. I had won a certificate for it so did not complain, besides had a 260 grain Brooks that my rifle really liked so not a pressing problem. The 350 legend is legal in Iowa for deer.
