Dave & ssb,
what would the hardness be compared to wheel weights?
Hi Len, some research shows:
1) Pure Lead @ 5 bhn
(2) Factory Swaged Lead @ 8.5 bhn
(3) Wheelweights @ 12.5 bhn
(4) Oregon Trails Laser cast bullets @ 22 bhn
The Ballistics Products buckshot is swaged lead with antimony to harden it to prevent deformation on firing. While pure lead can be work hardened a little, it anneals at room temperature and becomes soft again.
Regards,
Richard
