I am of the mind that Vit. N160 is perhaps a bit slow for this cartridge & know from the past I used H4895 & IMR3031 quite successfully. That was when I had a MSch M1903 stutzen twenty years ago.

This time, with my somewhat longer 23" barrel I opted for IMR4350 as a start....however, with the 160gn bullet roll crimped & an OAL of 2.950" approx, the load isn't yet completely satisfactory. Feed from magazine is fine, no pressure issues, just not quite accurate enough.
Don't know what MV is yet, but will chrono when I'm happy with the load.

While crimping will have some effect on increasing pressure, provided the load is safe, crimping is a good way to even out neck tension.
