I just got my first long gun. I got my brand new 110 Tactical 308 win. I am very very new to gun ownership. A little background, I was in the Navy for 21 years so I am no stranger to guns, stood many many watches armed and on a few different security teams etc. however I have never owned a gun until a couple of months ago when I got my first AR and 9mil. Anyways I have been reading a ton of opposing ideas when it comes to "breaking in" a new rifle.

I am hoping a few of you might be able to steer me in the right direction. Should I clean my new gun before shooting it for the first time? Is there an actual "breaking in" process? Anything you might pass on to a new gun owner (just to put you at ease, I am very familiar with gun safety etc etc, I am looking more for a maintenance path kind of insight)

Thank you all in advance for any tips, tricks, or suggestions you have to offer.
