leeenfield, well done man. Looks great and what a sweet hunting rifle it will be.

As for bullets that will work, I'd be thinking of the 220gr. Hornady or 200gr. Sierra FN's meant for the .375 Winchester, or - if wanting heavier bullets, the 235gr. Speer, perhaps with the lead nose bobbed and cupped at bit, if not just shot-as-is. should be able to get something like 2,400fps with them. In 9.3x57's tests, they proved quite a deep perpetrator when driven at that speed.
