Bertram would have brass and Woodleigh bullets. I don't think it would be a great problem.

I've never liked the .358's. Prefered the 9,3's and the .323 to .338, but for some reason like the .350 Rigby Magnum.

What I would use it on?

1. BGRC competitions.
2. Water buffalo - should work quite well.
3. Other bovines and the like.
4. Sambar - would work well.
5. Pigs and other deer species - over gunned
6. Moose, boar etc. Would work very well.
7. Larger antelope in Africa. What it was designed for.

Bullets are 200 gr to 250 gr, and I would think there are some 300 grs around.

Your experience with the .358 Norma Magnum would say what the similar round is capable of.
