I have been on the castboolits be site for awhile and have designed and sold a lot of cast bullet molds mostly for the s&w 500.
after getting a 357,375 and 445 supermags and loading what there is out there, I have noticed there is a lot of usable case space Being taken up by the body of the bullets and the heavy bullets could be designed better for more powder capacity and better down range trajectory.
just looking to see if there are enough people here and on the cast boolit site that would be interested to make it worth my time to design one for each of these calibers. Could do 414 also but not many people shoot those.
What I am looking at designing would also work great in the encore style guns, wouldn't work in standard 357or 44 due to the longer nose.
bullet weights I'll be 200-210 for 357, 250-265 for 375 and 300-310 for the 44. All set to work best with the 18.75 barrel twist on the supermags.

I use an LBT mould for my .375 SM. It's a WFN design and weight is 230 gr poured with coww. I'm the same user id on cast boolits....
Technically, the glass is always full; half liquid, half air....

Have mountain molds making me a new mold for the 375 since that one has so little to choose from.
had to call and talk to them to get what I wanted as their drawing program won't let you do to many mods to the nose and meplat.
will let you know how it work once I get it, they said about 4 weeks turn around.

MM does well. Do you have a PID? I was having issues with weight variances and once I got the PID for the pot, everything is within a grain for the most part. Seems the heat in the LEE was not keeping up with my casting cadence. All is well now.

Built a PID about 8 years ago, it works great in the Lee pot, time to get another pot and PID for hard and soft cast, pain to drain and clean everytme.

Well, im a bit late to this thread, but I do cast and will be casting for my SM. My initial loading of 296 under a 265 gr cast Keith bullet yielded just under 1600 fps (Hornaday data) but my standard deviations were a bit much at 40+ fps. Im planning to switch over to 2400 and work up starting from 21 gr until I get to about 1450 fps. I'll leave the top end stuff for the 296.
Im ordering a mold from Tom at Accurate Molds, which will be a variation on this....
I'll have the lube grooves expanded just a bit and also eliminate the front driving band shoulder. Probably (maybe/maybe not) decrease the meplat by .01 down to .35. My lead runs a consistent 12.5 hardness, and by sizing my bullets right and using good lube (Carnauba Red), I really don't have any leading issue to speak of. Plus, with the softer alloy, any lead that does get left in the barrel is easy to get out. The fastest I've run my bullets is 1750 in a 44 mag carbine, and it worked out great.
