Bullet barn has 9.3 cast possibly a few others. Good luck with your rifles it’s a great cartridge for just about everything walking here in North America.
I had to stop selling cast bullets last year.
I use a powder coated 250gr cast. Have pushed it to 2400fps in 9.3x57 using imr4895. The husqvarnas have quite a lot of variance in chamber and throat dimensions, most will digest a .368", some required .367" to chamber cleanly. Throats vary from tiny to 1/2".

Nice to hear from you Jet!!! I purchased decent amounts of bullets from you over the years. I’m almost done my supply of .475 400gr bullets in my 480 Ruger Redhawk. It force me to finally start using the moulds I’ve been acclimating the past few years lol.
Where was 250 grain 9.3 mould from?? I would love a 9.3 mould in something lighter than 286 for my 9.3x53R Swiss drilling.

The 9.3mm mold is from Accurate Molds. I can get the mold number if you want it. And I'd sell you the .475 mold if you need it, I have no use for it.
I’d love the mold number for that one. I have already purchased a .475 mold. Thanks though!!

You would have to work out an alloy that works with your load.
Depending on speed use a gas check and have a soft enough alloy with expand or at least deform when hitting game.
There are guys that use cast hollow point 45 ACP bullets that expand similarly to jacketed rounds, but it is based on alloy and hardness.
What would you use as a stand-in at the range to test the alloy for expansion? I've seen guys fill 4L milk jugs with water, but I'm not sure if that's the most accurate substitute? But, I would also not want to do the Paul Harrel meat target with the current cost of groceries (I also don't have a "new-and-improved-fleece-bullet-stop" lol)
Gel blocks. I'm sure you can find a recipe online if you don't want to buy a commercial product.
I use milk jugs though. The price is right, and while it's not the most accurate representation it gives me a consistent medium so I can compare how one bullet acts vs another. That way I can at least get an idea of which bullet will retain more weight, which bullet penetrated the most, etc. The way i see it as long at the medium is consistent it'll allow me to compare bullets - if bullet A retains more weight than bullet B in water, I feel safe assuming that will correlate to on-game performance even if the % weight retained isn't exactly the same between water and game.
Cast is a different world though, and I'd think about getting gel to get a better idea of on-game performance. With factory made jacketed bullets I know they're all designed to work at the velocities I'm using, i don't have to consider things like the alloy they're made of and if they'll expand or not.

It's hard to get a lead alloy to expand reliably at different velocities. You can experiment to get it just right at 100 yds, but then it might expand too fast at 50byds or not at all at 200 yds.
IMO, a flat nose cast bullet is more reliable for causing tissue damage on a game animal than a hollow point. The downside of a flat nose is reduced BC but if you aren't shooting long range it won't matter.
3031 is very good, so is 4895. Haven't tried 4198.
