300 blackout subsonic for deer?

[Trapperkid]

I’m looking at getting a Rossi single shot 300 blackout rifle to shoot deer under 70 yards in the woods. Does anyone have experience with this and what bullet did you use?

Maker bullets. I have not used a 300 bo as it’s not legal where I hunt deer. I have used makers in 360 bh and 45-70. Subs are different in that they can kill quite a long way out if you account for the drop. They simply don’t slow down quickly. Less drag at subsonic velocity.
