This question about lead or jacketed loading data for plated bullets is a complete joke! If anyone would compare the two, same bullet weight and powder, you will see that rarely is there a significant difference in charge weight between jacketed and lead. Hasn't anyone else noticed this, or does everyone just parrot what has been read on the internet? What is even stupider is manufacturers of plated bullets publish the same baloney. I guess no one selling plated bullets is a shooter!
As a matter of fact, it is not unusual, when pressure is the criteria, that the lead bullet data is .1-.2 gr. heavier than jacketed data!
