I hunt something similar in my back yard.
I use a 350 legend with subsonics when I’m not using my bow since I know my one of my neighbors is sensitive about it (she texts me about “all the baby deer” when she sees me walking back there to hunt), and I’m aware on how far a ricochet will go. My wife doesn’t hear any of the shots from 300yds away in the house and I get about 50-60yd range, which is all I need in the spot I’m hunting. I think we’re up to a dozen with it now and haven’t had any penetration issues with bullet performance. You may want to look at something similar. Growing up, people used buckshot for similar set ups but I don’t like the idea of 9-18 pellets bouncing through the woods as much as one slow bullet.
