That’s a hard question… 300blk is better than 5.56 (considering barrel length) IMO for the likely ranges id engage human targets in(likely close range, and hope to never find out). 8.6blk is my dear hunting round hands down. Where I’m at deer are 50-150 yards. 8.6blk is quiet and hits hard.
So 300blk for self defense… 8.6blk for hunting.
I live in SE NC. Duke energy has incentives for solar and they are about to pay for the installation of my Tesla charger in my garage… It’s not all bad I guess…
