It's a 308, and you are shooting deer.
Gonna have to try to screw up too badly, as long as they kill well,
It's not a failure. If too destructive, try again.
Not trying to derail, but it's the beauty of the 308/30-06 compared to
the highly touted(on the 'fire) tiny bores. You have the tool for the job,
without some fancy bullet or other tap dancing BS.
