I have my Dad's Remington 760 pump action in 30-06. It has a scope and I was thinking of finally getting around to checking it out and sighting it in etc. I always thought of this as the longest range firearm up in my little gun cabinet. Any tips on how to do that? I don't have a plan to actually go hunt with it currently, just want to check it out and do a standard sight in. Would you do this at 100 yards? 300 Yards? Second question, since 30-06 was invented 114 years ago. Are there common cartridges that are now clearly superior that if one were to go get a new hunting rifle for longer range use, that should be looked at ahead of 30-06. Something that could take, deer, black bear, possibly a moose if needed.
