[QUOTE="coyotezapper, post: 591750, member: 20438"] I have a Rem700 7mm STW that was a real fouler when I first got it. After 20 rounds accuracy went to hell. It would take upwards of ninety minutes to get the copper out. I then sent it off to 300 Below and had them cryo it. Cleaning / fouling is now minimal. Was this the result of the cryo treatment? Hard to say. It could be that the barrel was finally burnished properly. I have since lapped the bore with 3M polishing paper and fouling is similar to a custom tube. 1200 rounds now down the tube and accuracy is .5, .6 with two very different bullet types. I am curious to see how long the barrel will go. I expected it to be toast by now. I was told barrell life would be longer. Hmmm [/QUOTE]
