My 286s are vintage Norma soft point round nose. My 250 and 270 are original Speer soft points (I guess I'd have to call them vintage now also). I do have more "modern" 9.3s of various makes and models but these are for my 9.3x74R and see no reason to try them in my 9.3x57 as it is very happy with the first 3 mentioned. I find it interesting that 9.3s tend to shoot to about the same place no matter the load.
