Absolutely, except the alloy will have to be hard enough to not slump excessively.
That is why I suggested hardened WW - they can be made much harder than any commercial alloy. Monotype is about brinel 26 I think. Heated in the oven and quenched, WW bullets can be hardened up over 30 brinel. As long as they are sized and lubed immediately, they will not soften when sized.
If allowed to harden (12 hours after casting), then sized, the banks will be reduced to brinel 11 or 12 brinel or so.

Seems to me, LBT Blue lube is still available. It allowed me to load hardened cast bullets in my .375H&H up to 2,800fps and still shoot MOA.
