The exact barrel life of any given Remington barrel is almost impossible to predict. However, if standard, U.S. made factory loaded ammunition is used, and the barrel is properly cleaned after every use, one can expect to get anywhere from 2500 to 6000 rounds, before you will start to see your groups open up. The best thing to do is to keep a detailed record of rounds fired, and average group sizes. Once you start to see the groups open up, you can send the gun in to us for evaluation. Please understand that we are only referring to Remington production rifles, and we do not have a barrel life guarantee.
