Hard cast lead in 300 Blackout?

Are you interested in subs or supers.
Generally, it seems to be a mixed bag as far as results.
The gun is not really "cast friendly". Most 30 cal cast bullets are not the pointy profile that seem to feed best. The neck is real short and the twist rate is typically a lot faster than you would choose for anything in the 110 - 180 gr range. The throat on the chamber is also optimized for the 220 gr.
On the other hand, some people have had pretty good luck in spite of all of the above.
Not me.
I started with my own cast bullets in the 150 - 180 gr range. My boy's 1-7 twist 7.5" barrel did not like them at all.
I recently made a 10" 1-10 twist barrel from an old 30-06 and am trying low and mid range bullet weights. I did not have any luck in the first few outings, but I am still trying.

Yes.......and No. I cast for 300 using the Lee 225 grain spire point mold (the yes part) but I cast em about 16bhn for that round (the no part) so, not exactly hard cast, but cast non-the-less. They run well with a caveat, I have to seat them pretty deep to get them to run well in my barrel. I would certainly say go for it, but expect hickups of course.
