I have been trying out some round ball loads to work out a load for my 12 bore rifle ,
the only mould I could get hold of was RB 555gr in soft lead , I shot one of these @ 1765 Fps into a large block of hard wood & it was blowen half into splinters and the ball after digging it out of the soil still weighted 545gr and half round but a inch across !
I know this does not seem possible , is this normal for RB ? imagine hardened ball @ 1850 or so !

Do you guys who know think this is good enough for Water Buffalo ?
