338Rules,
There were two reasons:
1) I wasn't trying to produce the MOST velocity possible from a short-action 9.3. Instead I was just trying to duplicate the ballistics of the 9.3x62, since they'd been working well for a century, without excessive recoil. The .350 case has just about the same amount of powder room as the 9.3x62.
2) Charlie Sisk had found the .350 case fed even slicker than WSM cases in actions supposedly designed for short, fat, beltless magnums. I thought that might be handy in a rifle that might be used on dangerous game.
