Plated are definitely different than straight lead. My suggestion is to get both extreme bullets and zeros and see which your gun likes most or if there are no difference go with the extreme as they are cheaper and you can get them just about any time of the year. I have been shooting zeros for the last couple of years and have since switched to extreme just cause I can get them when I need them. Zeros are great bullets but they are hard, hard, hard to find. Hope that helps.
