DO NOT substitute Lead and Jacketed data for one another.
Lead seals the bore tighter, and because of its 'Sticky" nature, generates pressures higher and faster than Jacketed bullets
Look for published data, or multiple sources and then work up loads that are safe for YOUR weapon

Wes, I have never heard that before.

Any data or reports you’ve come across show that?

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


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

Yep, all my reload manuals.
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.
