Me personally im a 06 man. But the ol 308 is a great round ive used many times. Keep what feels best or youl likely regrett it. There aint a deer elk or bear out there that could tell the diffrence in getting hit with a 180gr 308 or a 180gr 30-06. As for the big brown bear they use to kill em with the 3030 and 44-40in the good ol days so a 308 would work maby not the ideal round but deqd is dead. If you like it better keep it.
