I do, 300 grain Lee mould, mmp sabot. I get my best accuracy by sizing them to .451. They drop .453 with my alloy. If I do my part a less then 1" group at 100 is the norm. At some distance you can hear the thump that big flat nose makes when it thumps a deer. If you want to try a few, shoot me a pm, I'll send you some.

I actually have the same mold and 280gr and a 230gr LBT molds from Verral Smith I shoot a ton of 45 long colts. I tried them all but go real accuracy maybe I'll try with the mmp sabot.
 
I was having problems also with accuracy, I tried them as cast .453 /.452 , then as a what the hay moment, I sized them to .451 and bam that's what it took.

I don't think I sized mine ill have to revisit it. Also I couldn't get any of the .451 or .452 commercial bullets to group well. Tried the .458 hornady 300 gr xtp in an orange sabot and it's a consistent 1in group 100 yard gun. I've never had a muzzleloader as picky as this cva optima
 
That's the fun part , figuring it out. If you can afford it now days.
Once I got the sizing figured , with the mmp sabot, they shoot good in all our guns, including my cva optima pistol.
 
Not sure about pure lead. I was just wanting some opinions on this. So far no one's chimed in about pure lead. I'm going to have to do more tests myself.
 
I’ve made a few molds years ago for some good friends wanting to cast and use in a sabot.
Basically, a Paper Patch bullet to me.
I use pure lead in ML for hunting. Pure is very mailable.
Wheel Weights are hard (rock), in a solid they will not expand much and if a HP they will fragment.
These were 350gr & 390gr, I believe.

The ML casting I’ve done to date is conicals and round balls. I’ve only ever used pure lead. I’m just getting around to trying sabots in my encore and I plan on using pure first.
