Starline stepped up to the plate for 357 Maxi brass last fall, Jamison might be another option.
I've been saying that Michigan laws are poised for someone to come out with a "357 Super-Duper-Maximum" with a case length of 1.8 inches and brass that is spec'ed to 65K PSI like the 460SW Magnum.
I've done a few hours of research trying to find a suitable parent case that I could trim to 1.8 inches, so that I could talk to someone like PT&G about a reamer... but my efforts so far have been futile.
Edit: I just want to point out that if I ever did come out with this wildcat, I surely would call it the 357 Super Duper Maximum.
Tromix is beta testing the 358 SOCOM. Necked down 50 Beowulf just like the 458 SOCOM. The 358 SOCOM pushes a 200 gr FTX @ 2500 fps. I'm assuming the draw of that as opposed to the 450b pushing a 200gr FTX @ 2500fps (with more frontal area= more TKO) is that the 358 would yield a better BC for longer shots without shedding so much velocity. I had some leftover loads from previous experiments that I use for foulers. Some times I have experiment loads that were a charge step (or two or three) too far and that's why they were leftovers. I usually put a note in the range box saying either foulers or pull down. Anyway, When I had my range day back on the 5th, before winter returned with a vengeance, I found three 230gr FMJ with stab crimps in a range box with no note. Figured what the heck, use them as foulers. I found out why they were leftovers after the first one flew out of the barrel at 2652 fps followed by the next one at 2650 (great SD). Those should have been puled down as well even though the primers were fine and the case heads had only grown .001 after I shot them. The velocity told me they were too stiff.Too much stress on the bolt. Anyway, where I was going was, my LabRadar chrony tracked them all the way to the 100yd target board. By the time they had made it 100 yds, they were already down to 1990 and 1981fps. A loss of ~650 fps That there is testimony to the BC penalty of round nose 451 bullets. The pointy, 325 FTX bullets, while starting out slower ~1700fps, only slowed ~250 fps. Something in a 35 caliber might do better given the longer length to diameter ratio.
Hoot
EDIT: Looked them up. The Hornady .358 200 gr FTX bullet has
twice the BC of the .452 200 gr FTX.
