Ideal calibre for (subsonic) culling?

[Ds J]

Hi Folks, which calibre/s would you recommend for culling on an eco estate? (Apologies if I have asked this before).

At times, subsonic shots out to 25m would be a requirement, and no shots over 100m. Shooting could also occur at night with appropriate lights etc.

Target species: antilope up to kudu and BlueWB.
