Searching through various posts on various topics, I've come across a lot of posts by people who comment on how many rounds they've put through their guns. I can see that this would come in handy if you wanted to sell it and be honest in telling potential buyer's the history of the gun, but is it really necessary or why else should I keep track of this? If you do, how do you guys keep track? Notepad, logbook, excel spreadsheet?
Just curious.
