jwp,
I know they make heavier 358 diameter bullets , I have some old 275 Grain Hornady RN bullets I may try just to see how they shoot .
It hasn't been a front burner project as my 9.3x62 covers the 286/320 grain range for me .
My Ruger is twisted 1 in 16 and haven't tried anything heavier that a 250 grain jacketed bullet yet .
Who knows, might build a 1 in 12 twist Whelen as a retirement project .
