Ok I know this has been beat to death and a lot of things have an effect on it. I currently have 1361 rounds on my 6slr barrel shooting retumbo and rl26. I use it in tactical type matches and a few prone matches. I have been trying to lay off shooting it to make the barrel last the summer. What is your guys take on the barrel lasting the summer (~1000rds). Shot 105 rdf's and now am shooting dtacs
