Archie,

Lead bullets MAY generate higher pressures than jacketed, but not always.

Generally, pressures with lead and jacketed bullet are in the same ball park.

Lyman's 47th edition Reloading Handbook has pressure data included as part of its loading specifications, and many lead bullet loads show pressures lower than with similar weight jacketed bullets using roughly the same powder charges, others show virtually identical pressures, and other loads show higher pressures.

There's simply no easy rule of thumb.
