Renington backs up nothing. I bought a new 700ML got it home and it would not fire but one out of three times. Took it back to the gun store the next day they said they would not take it back to call Remington. I called them and they told it was the caps. I told them I used three types and all misfired. They told me that I was loading the gun with bad or wet powder. I told them I it was new and sealed and works fine in my side cap gun. They said that there was no reported problems with that gun and it was my problem. I replaced the bolt spring with a aftermarket and the gun worked fine. So I sold it and I will never buy anything that Remington makes.
