Besides all the known 30-06 advantages, its eaier to load the 30-06 instead of fumbling with smaller cartridges and tiny actions.
Yep, it's great for the velcro sneakers set.
I must qualify for velcro sneakers then. I liked and preferred the shorter action advantages in theory for quite a few years, but discovered the advantages of the slightly longer cartridges and action when fumbling to reload with fingers that have all the dexterity of frozen hot dogs. Mostly, it doesn't matter, but when it matters, it matters!
