Dusty,
I don't know a thing about .303's, but PC gave me some poly coated flat points to try in my 03-A3 30-06 and they feed like butter.
All I had shot thru it before was factory pointy bullets (that's a technical term ;)).
I guess different rifles like different fodder.
Anyhow, those poly coated flat points are gonna be my standard reloads.
