A bit of tin helps the casting (and helped in the day.) Lead:tin at 40:1 is close to old revolver bullets. Creedmoor target rifle bullets were as much as 16:1 even though tin does not harden much. W.W. Greener recommended type metal for express rifle bullets, or hardening with mercury.

Powder compression of as much as 3/8" is common in black powder rifle cartridges, with consistent velocity and good accuracy. No guns blown up from "fines" that I have seen.
