Hello I am new rifle owner and never really shot one before but i recently bought a ruger american pred. and the cartridge is 6.5 creedmoor. Now i came across discussions about barrel life and was wondering as someone who is new to this would this really matter to me? does barrel life mean that when the barrel is shot out it would no longer work? lets say that i shot out the barrel and just keep shooting it what would happen? I most likely would never shoot past 300 yards. i just wanted something i can occasionally pickup and go to range and just have fun.
