300 blackout deer question

Currently, I have a sbr 300 blackout 8.2” barrel 1-7” twist to stabilize subs with a suppressor attached.

It shoots subs great but the supers are lacking on accuracy.

I was thinking about building a 16” upper a 1-8” twist to hunt deer with using supers.

So, shooting supers what would the max distance for deer hunting?

Thanks

150 yards is my opinion. Some say 200 but I think 150 is my comfortable max.

I hunt with a 8.5" blackout with 120 grain TSX. I limit myself to 150 yards because of the low power scope. I've killed hogs at 200 with my 16" bolt gun in blackout.
