A bit fast, but it will work. I would start with 58 gr and go from there. I have used 4895 for about 2800 fps.

4350 is a more appropriate speed powder.

Yes, 2800, and IMR4895 was always the most accurate powder in all three 358 Norma Mags I owned.

3031 has always been one of the best powders in several 358 Winchester rifles. Never tried it in the Nine Norma.

3031 would be a good powder if you were loading some reduced loads with lighter bullets (200 or 225 gr) for practice or maybe for deer. Another very good powder for the 225 to 250 gr bullets is IMR 4320
