@tibo , I dont know what the intended quarry is but with a low powered cartridge as above the effective range wont be too far on a Red Stag.
We need 1500 foot pounds energy and an impact velocity over 2200 fps as a safe minimum for an adult stag.
It was Col Townsend Whelan that came up with the 1000 fp, minimum but that was for Whitetail with heavy slow big cals around 1930
