    Typically lead bullets are sized 0.001" larger than groove dia. Berry's are pretty much pure lead /w a thin plating, so they are meant to be loaded like a lead bullet, often you will see them 0.001" larger than jacketed.

    They will work just fine... just don't load them too hot. What powder are you using?

    They will work fine, just don't load them using max jacketed data.
