Lead loads are normally LOWER for the same velocity.
Jacketed take more powder, as jacketed bullets do not seal the bore, are slicker, and allow for blow by, and a drop in chamber pressures.

Substituting jacketed data for lead is pretty common in the casting world.


Reloading...it’s like knitting for men.
